1E2fsprogs 1.41.14 (December 22, 2010) 2===================================== 3 4Fix spurious complaint in mke2fs where it would complain if the file 5system type "default" is not defined in mke2fs.conf. 6 7The resize2fs program will no longer clear the resize_inode feature 8when the number reserved group descriptor blocks reaches zero. This 9allows for subsequent shrinks of the file system to work cleanly for 10flex_bg file systems. 11 12The resize2fs program now handles devices which are exactly 16T; 13previously it would give an error saying that the file system was too 14big. 15 16E2fsck (and the libext2fs library) will not use the extended rec_len 17encoding for file systems whose block size is less than 64k, for 18consistency with the kernel. 19 20Programming notes 21----------------- 22 23E2fsprogs 1.41.13 would not compile on big-endian systems. This has 24been fixed. (Addresses Sourceforge Bug: #3138115) 25 26The ext2fs_block_iterator2() function passed an incorrect ref_offset 27to its callback function in the case of sparse files. (Addresses 28Sourceforge Bug: #3081087) 29 30Fix some type-punning warnings generated by newer versions of gcc. 31 32 33E2fsprogs 1.41.13 (December 13, 2010) 34===================================== 35 36E2fsck now supports the extended option "-E journal_only", which 37causes it to only do a journal replay. This is useful for scripts 38that want to first replay the journal and then check to see if it 39contains errors. 40 41E2fsck will now support UUID= and LABEL= specifiers for the -j option 42(which specifies where to find the external journal). (Addresses 43Debian Bug #559315) 44 45E2fsck now has support for the problems/<problem code>/force_no 46configuration option in e2fsck.conf, which forces a problem to not be 47fixed. 48 49Dumpe2fs will now avoid printing large negative offsets for the bitmap 50blocks and instead print a message which is a bit more helpful for 51flex_bg file systems. 52 53Mke2fs will now check the file system type (specified with the -t 54option) to make sure it is defined in the mke2fs.conf file; if it is 55not, it will print an error and abort. If the usage type (specified 56with the -T option) is not defined in mke2fs.conf, mke2fs will print a 57warning but will continue. (Addresses Debian Bug #594609) 58 59Clarified error message from resize2fs clarifying that on-line 60shrinking is not supported at all. (Addresses Debian Bug #599786) 61 62Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be 63displayed. (Addresses Debian Bug #555456) 64 65E2fsck will open the external journal in exclusive mode, to prevent 66the journal from getting truncated while it is in use due to a user 67accidentally trying to run e2fsck on a snapshotted file system volume. 68(Addresses Debian Bug #587531) 69 70Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL 71flag. 72 73The tune2fs program can now set the uninit_bg feature without 74requiring an fsck. 75 76The tune2fs, dumpe2fs, and debugfs programs now support the new ext4 77default mount options settings which were added in 2.6.35. 78 79The e2fsck and dumpe2fs programs now support the new ext4 superblock 80fields which track where and when the first and most recent file 81system errors occurred. These fields are displayed by dumpe2fs and 82cleared by e2fsck. These new superblock fields were added in 2.6.36. 83 84Debugfs now uses a more concicse format for listing extents in its 85stat command. This format also includes the interior extent tree 86blocks, which previously was missing from stat's output for 87extent-based files. 88 89Debugfs has a new option, -D, which will request Direct I/O access of 90the file system. 91 92Mke2fs will skip initializing the inode table if a device supports 93discard and the discard operation will result in zero'ed blocks. 94 95Badblocks will now correctly backspace over UTF-8 characters when 96displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses 97Debian Bugs #583782 and #587834) 98 99E2freefrag will now display the total number of free extents. 100 101Resize2fs -P no longer requires a freshly checked filesystem before 102printing the minimum resize size. 103 104Fixed a floating point precision error in a binary tree search routine 105that can lead to seg fault in e2fsck and resize2fs. 106 107Fixed a bug in e2fsck where if both the original and backup superblock 108are invalid in some way, e2fsck will fail going back to the original 109superblock because it didn't close the backup superblock first, and 110the exclusive open prevented the file system from being reopened. 111 112Fixed a big in e2freefrag which caused getopt parsing to fail on 113architectures with unsigned chars. (Addresses Gentoo Bug: #299386) 114 115Clarified an mke2fs error message so a missed common in an -E option 116(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1") 117results in a more understandable explanation to the user. 118 119Mke2fs now displays the correct valid inode ratio range when 120complaining about an invalid inode ratio specified by the user. 121 122Mke2fs now understands the extended option "discard" and "nodiscard", 123and the older option -K is deprecated. The default of whether 124discards are enabled by default can be controled by the mke2fs.conf 125file. 126 127Mke2fs's handling of logical and physical sector sizes has been 128improved to reflect the fact that there will be some SSD's with 8k and 12916k physical sectors arriving soon. Mke2fs will no longer force block 130size to be the physical sector size, since there will be devices where 131the physical sector size is larger than the system's page size, and 132hence larger than the maximal supported block size. In addition, if 133the minimal and optimal io size are not exported by the device, and 134the physical sector size is larger than the block size, the physical 135sector size will be used to set the Raid I/O optimization hints in the 136superblock. 137 138E2fsck will now display a better, more specific error message when the 139user enters a typo'ed device name, instead of blathering on about 140alternate superblocks. 141 142Fixed various Debian Packaging Issues 143 144Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004, 145#589345, #591083; Addresses Launchpad Bug: #505719) 146 147Update the Chinese, Chzech, Dutch, French, Germany, Indonesian, 148Polish, Swedish, and Vietnamese translations. 149 150 151Programmer's Notes 152------------------ 153 154Fix a dependency definition for the static and profiled blkid 155libraries which could cause compile failures in some configurations. 156(Addresses Debian Bug: #604629) 157 158Add support for Direct I/O in the Unix I/O access layer. 159 160Fixed a memory leak in the Unix I/O layer when changing block sizes. 161 162Fixed minor memory leaks in mke2fs. 163 164Added a new function to the ext2fs library, ext2fs_get_memalign(). 165 166The tst_super_size test program will check to make sure the superblock 167fields are correctly aligned and will print them out so they can be 168manually checked for correctness. 169 170Fixed some makefile dependencies for test programs in lib/ext2fs. 171 172Reserved the feature flags and superblock fields needed for the Next3 173snapshot feature. 174 175Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and 176EXT4_INCOMPAT_EA_INODE. 177 178 179E2fsprogs 1.41.12 (May 17, 2010) 180================================ 181 182Mke2fs now gives a correct error message if the external journal 183device is not found. (Addresses Red Hat Bug #572935) 184 185Resize2fs -P will now refuse to print a minimum size if the file 186system is not clean. Previously it would go ahead and print a minimum 187size anyway, which might not be correct, leading to user confusion. 188 189E2fsck now tests for extents that begin at physical block 0 and 190rejects them as invalid. (Addresses Google Bug: #2573806) 191 192Fixed a bug in e2fsck which could cause it to crash when trying to 193remove an invalid extent and the block bitmaps hadn't yet been loaded. 194(Addresses SourceForge Bug: #2971800) 195 196E2fsck now will completely skip time-based checks if the system clock 197looks insane or the option broken_system_clock is set in 198/etc/e2fsck.conf. 199 200E2fsck would previously report an i_blocks corruption for a 4T file 201created using posix_fallocate; this bug has been fixed. 202 203E2fsck will now correctly mark a sparse journal as invalid and will 204delete and recreate the journal to address the problem. 205 206E2fsck would previously incorrectly ask the user whether she would 207like to abort the file system check after finding a problem --- and 208then abort regardless of the user's answer. This is annoying, and 209has been fixed. 210 211E2fsck can now continue even if it fails to recreate the resize 212inode; previously it would just abort the file system check 213altogether. 214 215E2fsck could potentially remove directory entries for inodes found in 216the unused region of the inode table; this would generally happen on 217ext4 file systems that do not use journaling. This bug has been fixed 218by not clearing these directory entries once it has been established 219that bg_unused_inodes may not be trustworthy; once pass #2 has been 220completed, e2fsck will restart the file system check from the 221beginning, and then it will be safe to delete any directory entries 222pointing to inodes that appear to be deleted. (Addresses Google Bug: 223#2642165) 224 225E2fsck will not try to set the block group checksums if the user 226cancels the fsck with a control-C. It's a bad idea to set the 227checksums if e2fsck hasn't been completed, and it often results an the 228error message, "Inode bitmap not loaded while setting block group 229checksum info". (Addresses Launchpad Bug: #582035) 230 231The mke2fs program now queries the kernel for the physical as well as 232the logical sector size, and will not allow a blocksize below the 233logical, and will strongly encourage a blocksize at least as big as 234the physical blocksize. This is needed for 4k sector drives that 235emulate 512 byte sector sizes. 236 237Mke2fs will now allow a flex_bg size of 1. This is unusual, and 238rarely needed, but it is a legal value. 239 240E2fsck will check for cases where the EOFBLOCKS_FL is set when it is 241not needed, and offer to clear it; this is a sign of a kernel bug, but 242more importantly, some released kernels may crash when this situation 243is encountered on ext4 file systems. (Addresses Google Bug: #2604224) 244 245E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether 246i_size is correct. (Kernels starting with 2.6.34 will set 247EOFBLOCKS_FL.) 248 249The com_err library will now only output ^M (a CR character) when the 250tty is in raw mode. 251 252Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish, 253and Vietnamese translations. 254 255Fixed various Debian packaging issues --- see debian/changelog for 256details. (Addresses Debian Bugs: #571247, #563487) 257 258 259Programmer's Notes 260------------------ 261 262The regression test suite now uses its own mke2fs.conf file, so that 263downstream distributions want change the mke2fs.conf file which is 264distributed in the RPM or dpkg file, without worrying about screwing 265up the regression test results. 266 267Always build namei.o so that building with configure --disable-debugfs 268works correctly. Long-term, if we care about reduced e2fsprogs 269builds, we need a more general solution for deciding what .o files are 270needed for a particular build. Given that install floppies are going 271(gone?) the way the dodo bird, we probably don't care, though. 272(Addresses Sourceforge Bug: #2911433) 273 274Add configure options --enable-symlink-build and 275--enable-symlink-install, which allow e2fsprogs be built using 276symlinks instad of hard links, and to be installed using symlinks 277instead of hard links, respectively. It is useful when the file 278system where the build is taking place, or the file system where 279e2fsprogs is installed, can't handle hard links for some reason. 280(Addresses Sourceforge Bug: #1436294) 281 282Fixed compile warning in mke2fs.c. 283 284 285E2fsprogs 1.41.11 (March 14, 2010) 286================================== 287 288E2fsck will no longer give a fatal error and abort if the physical 289device has been resized beyond 2**32 blocks. (Addresses Launchpad 290Bug: #521648) 291 292Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows 293the allocation status of the block <blk>. (Addresses Debian Bug: 294#564084) 295 296E2fsck now prints a much more emphatic and hopefully scary message 297when a file system is detected as mounted while doing a read/write 298check of the filesystem. Hopefully this will dissuade users from 299thinking, "surely that message doesn't apply to *me*" :-( 300 301E2fsck -n will now always open the file system read-only. We now 302disallow certain combination of options which previously were manual 303exceptions; this is bad because it causes users to think they are 304smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n 305-D" are no longer supported. (Addresses Launchpad Bug: #537483) 306 307In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if 308it detected a badly aligned partition. Unfortunately, this broke some 309distribution installation scripts, so it now just prints the warning 310message and proceeds. (Addresses Red Hat Bug: #569021. Addresses 311Launchpad Bug: #530071) 312 313Mke2fs would take a long time to create very large journal files for 314ext4. This was caused by a bug in ext2fs_block_iterate2(), which is 315now fixed. 316 317E2fsck now understands the EOFBLOCKS_FL flag which will be used in 3182.6.34 kernels to make e2fsck not complain about blocks deliberately 319fallocated() beyond an inode's i_size. 320 321E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where 322e2fsck -fD can corrupt non-indexed directories when are exists one or 323more file names which alphabetically sort before ".". This can happen 324with ext2 filesystems or for small directories (take less than a lock) 325which contain filenames that begin with a space or some other 326punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad 327Bug: #525114) 328 329 330Programmer's Notes 331------------------ 332 333Add new test, f_rehash_dir, which checks to make sure e2fsck -D works 334correctly. 335 336The libcom_err function now has support for Heimdal's com_right_r 337function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian 338Bug: #558910) 339 340 341E2fsprogs 1.41.10 (February 7, 2010) 342==================================== 343 344Fix resize2fs bug which causes it to access invalid memory. 345 346Add libss support for libreadline.so.6. 347 348Fix e2fsck's check for extent-mapped directory with an incorrect file 349type. 350 351Add new e2fsck.conf configuration option, default/broken_system_clock 352to support systems with broken CMOS hardware clocks. Also, since too 353many distributions seem to have broken virtualization scripts now, 354e2fsck will by default accept dates which are off by up to 24 hours by 355default. (Addresses Debian Bugs: #559776, #557636) 356 357Fix a bug where mke2fs may not use the best placement of the inode 358table when there is only room for a single block group in the last 359flex_bg. 360 361E2fsck is now smarter when it needs to allocate blocks in the course 362of fixing file system problems. This reduces the number of spurious 363differences found in pass #5. 364 365E2fsck will no longer rehash directories which fit in a single 366directory block. 367 368E2fsck now correctly handles holes in extent-mapped directories (i.e., 369sparse directories which use extents). 370 371Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2(). 372 373Fix a bug in filefrag where on platforms which can allow file systems 374with 8k blocks, that it doesn't core dump when it sees a file system 375with 8k block sizes. (Thanks to Mikulas Patocka for pointing this 376out.) 377 378E2fsck will correctly fix directories that are have an inaccurate 379i_size as well as other problems in a single pass, instead of 380requiring two e2fsck runs before the file system is fully fixed. 381 382Fix e2fsck so it will correctly find and detect duplicate directory 383entries for non-indexed directories. ( Addresses Sourceforge Bug: 384#2862551) 385 386Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or 387thinly-provisioned storage device.

(Addresses SourceForge Bug: #2871782) 420 421Mke2fs now will obtain get device topology information from blkid and 422use it to populate the superblock stride and stripe sizes.

This fix causes e2fsck to try to find space for a new 483portion of the inode table in the containing flex_bg, and if that 484fails, the new portion of the inode table will be allocated in any 485free space available in the filesystem. 486 487Make e2fsck less annoying by only asking for permission to relocate a 488block group's inode table once, instead of for every overlapping 489block. Similarly, only ask once to recompute the block group 490checksums, instead of once for each corrupted block group's checksum. 491 492Fix filefrag to avoid print the extent header if the FIEMAP ioctl is 493not present, and it needs to fall back to using the FIBMAP ioctl. 494 495Fix filefrag to correctly print the number of extents for zero-length 496files.

Also add 573safety checks so that if the unix domain socket between the uuid 574library and uuidd program is closed for any reason, both the library 575and the uuidd will return an appropriate error code instead of looping 576in an infinite loop. 577 578The e2croncheck script, which creates an LVM snapshot and then checks 579the ext3/4 filesystem via the LVM snapshot, has been added to the 580contrib directory. 581 582Fix filefrag program for files that have more than 144 extents. 583 584Update French, Polish, Czech, Indonsian, and Sweedish translation from 585the Translation Project. 586 587Fixed various Debian packaging issues --- see debian/changelog for 588details.

(Addresses Sourceforge Patches: #2813809) 605 606Enhance the build system so that the full set of commands executed by 607the Makefiles are displayed, instead of the Linux kernel summary 608output, if the build was configured with --enable-verbose-makecmds, or 609if GNU make is in use and the V variable is non-null, i.e., via "make 610V=1". 611 612 613E2fsprogs 1.41.7 (June 29, 2009) 614================================ 615 616Fix a bug in libext2fs which can cause e2fsck and resize2fs to write 617uninitalized data into the portion of the inode beyond the first 128 618bytes when operating on inodes mapped via extents; potentially 619corrupting filesystems. 620 621Fix memory leaks in e2fsprogs, including a very large memory leak 622which can cause e2fsck to run out of memory when checking very large 623filesystems using extents. 624 625The logsave program will now filter out the ^A and ^B characters when 626writing to the console. 627 628Harden ext2fs_validate_entry() so that lsdel will not read beyond the 629end of the block even if the directory block is corrupted. 630 631Fix debugfs from core dumping if the logdump command fails to open the 632output file. 633 634Enhance badblocks to print the currently tested block number when 635interrupted with ^C. 636 637Fix lsattr to exit with a non-zero status when it encounters errors. 638(Addresses RedHat Bugzilla #489841) 639 640Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger) 641filesystems as the kernel when encoding rec_len >= 64k. For 64k 642filesystems (currently all that is supported by e2fsprogs, this is 643only a minor corner case). 644 645Resize2fs will now update the journal backup fileds in the sup0erblock 646if the journal is moved; this avoids an unnecessary full fsck after 647resizing the filesystem.

(Addresses Sourceforge Bug: #2791794) 685 686Fix e2fsck to restart only once in the case of multiple block groups 687which inodes in use that are in the uninitialized part of the block 688group's inode table. 689 690To reduce user confusion, if the /etc/mtab file is missing 691ext2fs_check_mount_point and ext2fs_check_if_mounted will return a 692new, explicit error code to indicate this case. This will cause 693e2fsck to give a clearer error message when the user is using buggy 694rescue CD's that don't properly set up /etc/mtab. (Addresses Debian 695Bug: #527859) 696 697Fix e2fsck so that if the primary group descriptors are corrupted, but 698the backup superblock is entirely invalid, to go back to using (and 699fixing) the priary group descriptors instead of completely giving up 700on the filesystem. (Addresses Debian Bug: #516820) 701 702Change e2fsck to not abort a preen pass if an inode is found to have 703i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer 704kernels (post 2.6.29) will ignore this field. So let's fix it 705automatically during the preen pass instead of forcing the user to fix 706this up manually. (Addresses Debian Bug: #526524) 707 708Add resource tracking for e2fsck passes 1b through 1d. 709 710Speed up e2fsck by eliminating unnecessary journal checks if the 711filesystem is already mounted and doesn't need recovery (since the 712kernel would have run the journal when the filesystem was mounted.) 713Also speed up e2fsck by avoiding unnecessary block group descriptor 714updates in ext2fs_close(). 715 716Add support to chattr to migrate inodes from using direct/indirect 717blocks to extents. 718 719Avoid corrupting the filesystem if there is an attempt to shrink a 720filesystem using resize2fs smaller than posible by making 721ext2fs_set_bmap() more careful not to delete the old block until the 722new block can be inserted. In addition, fix a bug in how the minimum 723size of the filesystem (plus a safety margin) is calculated, and 724modify resize2fs to refuse to shrink the filesystem below that minimum 725size without the force flag. 726 727Teach blkid to try to figure out DM device names using take advantage 728of information in sysfs when running on kernels (2.6.29 and later) 729which provide this information in /sys/block/dm-<N>/dm/name; this is 730much faster than scanning for the devncie number in /dev/mapper. 731 732Fix blkid to prefer /dev/mapper/<name> device names instad of the 733private /dev/dm-X names. 734 735Add an -a option to debugfs's close_filesys command which writes any 736changes to the superblock or block group descriptors to all of the 737backup superblock locations. 738 739Add support to the filefrag program to use the FIEMAP ioctl. 740 741Update Chinese translation from the Translation Project. 742 743Clean up various man pages.

(Addresses Sourceforge Bug #2484331) 767 768Update the config.guess and config.sub file to the latest from the 769FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses 770Debian Bug: #528330) 771 772Add a new function, ext2fs_extent_open2(), which behaves like 773pext2fs_extent_open(), but uses the user-supplied inode structure 774when opening an extent instead of reading the inode from disk. 775 776 777E2fsprogs 1.41.5 (April 23, 2009) 778================================= 779 780Fix a number of filesystem corruption bugs in resize2fs when growing 781or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem 782is not mounted). 783 784Debugfs can now set i_file_acl_high via the set_inodes_field command, 785and print a 64-bit file acl. This is useful for debugging filesystem 786corruptions where the high bits of i_file_acl_high are set. E2fsck 787will detect and fix non-zero i_file_acl_high on 32-bit filesystems 788since some Linux kernel versions pay attention to this field even when 789they shouldn't. 790 791Speed up e2fsck when checking clean filesystems by avoiding 792unnecessary block reads, and coalescing the block group descriptor 793blocks so they are read using a single read operation. 794 795The libuuid library will now close all file descriptors before running 796uuidd. This avoids problems when the calling program has open sockets 797which then never get closed because uuidd is a long-running helper 798daeomn. (Addresses Launchpad bug: #305057) 799 800In order to avoid unnecessary full filesystem checks by e2fsck after 801an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on 802the backup superblocks. (Addresses Red Hat Bugzilla: #471925) 803 804Mke2fs will avoid trying to create the journal when run in 805superblock-only mode (mke2fs -S), since the left-over journal in the 806inode table will cause mke2fs to fail. 807 808Fix a bug in libext2fs functions that check to see if a particular 809device or filesystem image is mounted, which would cause these 810functions to report that a file identical to the (relative) pathname 811used by a pseudo-filesystem was mounted when in fact it was not. 812 813Update Czech translation from the Translation Project. 814 815Add Chinese (simplified) translation from the Translation Project. 816 817Fix support for external journals (which was broken in e2fsprogs 8181.41.4). 819 820Fix a regression in debugfs where the "stat" command when no 821filesystem was open would cause debugfs to crash with a segmentation 822violation. 823 824Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be 825used to support filesystems without a journal. Update the blkid 826library so it understands this. 827 828The blkid library will remove an entry from the blkid cache 829representing the entire disk if partitions are found, since presuambly 830the device previously had no partition table, but has now transitioned 831to using a partition table. 832 833Add a check to mke2fs and tune2fs that the argument to the -m option 834(which specifies the reserved ratio) must be greater than zero. 835(Addresses Debian Bug: #517015) 836 837Add support for tracking the number kilobytes written to the 838filesystem via the superblock field s_kbytes_written. It will be 839updated by the kernel as well as by e2fsprogs programs which write to 840the filesystem. This is useful for tracking the wear to filesystems 841on Solid Sstate Drives. 842 843Fix compatibility issue in the libext2fs info file and makeinfo 844version 4.12.

(This is a limitation in the current implementation 890of tune2fs -I.) 891 892E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4 893filesystems with 32-bit block numbers, when the headers for 64-bit 894block numbers was added. This regression has been fixed. 895 896Debugfs's ncheck command has been fixed to avoid printing garbage 897characters at the end of file names. 898 899Fix resize2fs for ext4 filesystems. Some blocks that that need moving 900when shrinking filesystems with uninit_bg feature would not be moved. 901In addition, blocks and inode table blocks were not being correctly 902freed when shrinking filesystems with the flex_bg feable, which caused 903resize2fs -M to fail. Finally, when blocks are moved, make sure the 904uninitialized flag in extents is preserved. 905 906Fix bug which caused dumpe2fs to abort with an error if run on a 907filesystem that contained an external journal. 908 909Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check 910for this in argv[0] to provide better legacy support for these 911distributions. This is a practice that should NOT be continued, 912however. 913 914Mke2fs now has a new option -U, which allows the user to specify the 915UUID that should be used for the new filesystem. 916 917Mke2fs will treat devices that are exactly 16TB as if they were 16TB 918minus one block. This allows users who have read that ext3 supports 919up to 16TB filesystems and who create a 16TB LVM to not get confused, 920since the true limit is really 16TB minus one block. 921 922E2fsck will no longer abort an fsck run if block group has an errant 923INODE_UNINIT flag. 924 925E2fsck now distinguishes between fragmented directories and fragmented 926files in verbose mode statistics and in the fragcheck report. 927 928Fix a bug in e2fsck which casued it double count non-contiguous 929extent-based inodes. 930 931E2fsck will leave some slack space when repacking directories to allow 932room for a few directory entries to be added without causing leaf 933nodes to be split right away. 934 935Fix a bug which caused e2fsck to crash when it comes across a 936corrupted interior node in an extent tree with the error message: 937"Error1: Corrupt extent header on inode XXXXXX" 938 939E2fsck problem descriptions involving the journal are no longer 940referred to as "ext3" problems, since ext4 filesystems also have 941journals. 942 943Fix a long-standing bug in e2fsck which would cause it to crash when 944replying journals for filesystems with block sizes greater than 8k. 945 946Update Catalan translation from the Translation Project. 947 948Fixed various Debian packaging issues --- see debian/changelog for 949details. (Addresses Debian Bugs: #503057, #502323, #511207) 950 951Programmer's Notes 952------------------ 953 954Fix build of e2fsck.profiled, and add support for building profiled 955binaries in the misc directory if configured with --enable-profile. 956 957The ext2fs_open() function now performs more sanity checks on the 958superblock to avoid potential divide by zero errors by other parts of 959library. 960 961The ext2fs_read_inode_full() function now has a safety check to avoid 962a segmentation fault on corrupted filesystems. 963 964The ext2fs_new_inode() function now has a sanity check so that if the 965s_first_inode field in the superblock is insane, it will return 966EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number. 967 968To avoid segmentation faults, ext2fs_block_alloc_stats() and 969ext2fs_inode_alloc_stats() now validates the passed inode or block 970number to avoid overrunning an array boundary. 971 972Various signed/unsigned errors for variables containing block numbers 973have been fixed. 974 975Accomodations for gcc's stupidity in not realizing that constant 976strings that do not contain a '%' character are safe to use in format 977strings have been made so that distributions that want to compile 978e2fsprogs with -Werror=format-security have an easier time doing so. 979 980Added a new 64-bit getsize interface, ext2fs_get_device_size2(). 981 982Added the utility make-sparse.c to the contrib directory. 983 984The ext2fs_block_iterate2() function now reflects errors from 985ext2fs_extent_set_bmap() to the caller, if the callback tries to 986change a block on an extent-based file, and ext2fs_extent_set_bmap() 987fails for some reason (for example, there isn't enough disk space to 988split a node and expand the extent tree. 989 990The ext2fs_block_iterate2() function will preserve the uninit flag in 991extents when the callback function modifies a block in an extent-based 992file. 993 994E2fsck will now flag filesystems that have an insane s_first_ino field 995in their superblock, and attempt to use a backup superblock to repair 996the filesystem. 997 998 999E2fsprogs 1.41.3 (October 12, 2008) 1000=================================== 1001 1002E2fsck has been fixed so it prints the correct inode number for 1003uinit_bg related problems. 1004 1005E2fsck will now offer to clear the test_fs flag if the ext4 filesystem 1006is available on linux. This can be disabled via a configuration 1007option in /etc/e2fsck.conf. 1008 1009Fix a file descriptor leak in libblkid when checking to see if an ext4 1010or ext4dev module exists. 1011 1012Fix a bug in e2fsck where in preen mode, if there are disk I/O errors 1013while trying to close a filesystem can lead to infinite loops. 1014(Addresses Red Hat Bugzilla #465679) 1015 1016Fix a bug in resize2fs where passing in a bogus new size of 0 blocks 1017will cause resize2fs to drop into an infinite loop.

This fixes a regression 1045from e2fsprogs 1.40.7 which caused e2fsck to fail if the user 1046specifies a block number using the -b option if the blocksize option 1047isn't also specified using -B. Unfortunately, users very commonly 1048invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup 1049superblock; in fack e2fsck will often suggest this kind of command 1050line. Oops. 1051 1052Enhance the debugfs's "ncheck" command so it will print all of the 1053pathnames for the specified inodes. (Previously, in some cases ncheck 1054might not print a pathname for an inode at all if some of the other 1055inodes had multiple hard links.) 1056 1057Enhance debugfs's "hash" command so the hash seed can be specified via 1058a command-line option. In addition, allow the hash algorithm to be 1059specified by name instead of just by number. 1060 1061Fix e2fsck so that we don't accidentally print the translation file's 1062header when asking the user a custom question so there is no prompt 1063defined for a particular problem record.

Also make 1143gen-tarball print the size of the resulting tar.gz file. 1144 1145 1146E2fsprogs 1.41.1 (September 1, 2008) 1147==================================== 1148 1149Many people are forgetting to update their mke2fs.conf file, and this 1150causes ext3, ext4, and ext4dev filesystems won't get created with the 1151proper features enabled. We address this in two ways. First, mke2fs 1152will issue a warning if there is not definition for an ext3, ext4, or 1153ext4dev filesystem and the user is trying to create such a filesystem 1154type. Secondly, when installing from a source build, "make install" 1155will provide basic configuration file handling for /etc/mke2fs.conf. 1156If it exists, and does not mention ext4dev, it will be moved aside to 1157/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will 1158be installed. If the existing /etc/mke2fs.conf file does mention 1159ext4dev, then "make install" will install official mke2fs.conf file as 1160/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that 1161they should look to see if any changes need to be merged. 1162 1163The mke2fs program will now create the journal in the middle of the 1164filesystem, since this minimizes seek times on average for fsync-heavy 1165workloads. In addition, mke2fs will now create journals using extents 1166for filesystems that support them. This results in a more efficient 1167encoding for the journal since it eliminates the need for using 1168indirect blocks. 1169 1170The mke2fs program will avoid allocating an extra block to the 1171journal. (Addresses Sourceforge Bug: #1483791) 1172 1173Mke2fs will correctly enforce the prohibition against features 1174(specifically read-only features) in revision 0 filesystems. (Thanks 1175to Benno Schulenberg for noticing this problem.) 1176 1177Mke2fs previously would occasionaly create some slightly non-optimally 1178placed inode tables; this bug has been fixed. 1179 1180The mke2fs and tune2fs programs now print the correct usage message 1181describing the maximum journal size. (Addresses Debian Bug: #491620) 1182 1183Add support for setting the default hash algorithm used in b-tree 1184directories in tune2fs (from a command-line option) or mke2fs (via 1185mke2fs.conf). In addition, change the default hash algorithm to 1186half_md4, since it is faster and better. 1187 1188The blkid library will now recognize MacOS hfsx filesystems, and 1189correctly extract the label and uuid for hfs, hfsx, and hfsplus 1190filesystems. (Addresses Sourceforge Feature Requests: #2060292) 1191 1192The blkid library has improved detection of JFS and HPFS filesystems. 1193(Addresses Launchpad Bug: #255255) 1194 1195The blkid library is now much more efficiently handling devicemapper 1196devices, mainly by no longer using the devicemapper library. This can 1197speed up access for systems with a large number of device mapper 1198devices. 1199 1200Blkid had a number of cache validation bugs in libblkid that have been 1201fixed. (Addresses Debian Bug: #493216) 1202 1203Resize2fs will now properly close out the "updating inode references" 1204progress bar so there is a newline printed before printing the final 1205"resize is successful" message. 1206 1207Resize2fs will now correctly handle filesystems with extents and/o 1208uninitialized block groups correctly when file/directory blocks need 1209to relocated (i.e., when shrinking a filesystem or if the resize_inode 1210is not present). To support this, the ext2fs library now supports 1211initializing inode and block bitmaps that are not yet initialized when 1212allocating them using ext2fs_new_block() and ext2fs_new_inode(). In 1213addition, e2fs_block_iterate2() can now support changing the location 1214of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has 1215been optimized to avoid creating unnecessary new extents when updating 1216the location of blocks in the extent tree. This will also help out 1217e2fsck's recovery of obscurely corrupted filesystems with extents, 1218when blocks are claimed by multiple inodes. 1219 1220Add support for on-line resizing ext4 filesystem with the flex_bg 1221filesystem feature. The method for doing so is not optimal, but to do 1222a better job will require kernel support. 1223 1224E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and 1225debugfs programs to not be able to read e2image files; the signed 1226vs. unsigned bug in the code which read bitmaps from the e2image has 1227been fixed. (Addresses Debian Bug: #495830) 1228 1229Resize2fs is now correctly managing the directory in-use counts when 1230shrinking filesystems and directory inodes needed to be moved from one 1231block group to another. This bug has been around since e2fsprogs 12321.26, and is largely harmless, but does cause a filesystem corruption 1233which will be flagged by e2fsck after the filesystem has been shrunk. 1234 1235E2fsck will no longer issue spurious complaints about the inode size 1236caused by very large extent-based files, and by blocks reallocated 1237using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses 1238Kernel Bugzilla: #11341) 1239 1240Mke2fs will now set the creation timestamp on the lost+found directory 1241and the root directory. (More generally, all new inodes created using 1242the ext2fs library will correctly set the creation timestamp.) 1243 1244E2fsck now correctly calculates ind/dind/tind statistics in the 1245presence of extent-based files. In addition, "e2fsck -v" will report 1246statistics of the depth of extent trees in the filesystem. E2fsck can 1247also give an inode fragmentation report using "e2fsck -E fragcheck" 1248which can be useful when debugging the kernel block allocation 1249routines. 1250 1251Fix support for empty directory blocks in ext4 filesystems with 64k 1252blocksize filesystems. 1253 1254E2fsck will now print the depth of corrupt htree directories. 1255 1256Debugfs's htree command now correctly understands extent-based 1257directories. It will also print out the minor hash as well as the 1258major hash. 1259 1260Debugfs has a new command which will print the supported features of 1261e2fsprogs, to enable scripts to know whether the installed version of 1262e2fsprogs can support a specific feature. 1263 1264Debugfs will now write files using extents for filesystems that 1265support them. 1266 1267The error message printed by "tune2fs -I" if the inode size was too 1268small was rather confusing, so it has been improved. Also, we won't 1269try to create an undo log until we know that command-line-specified 1270parameters such as "tune2fs -I <inode size>" are valid. 1271 1272Given some filesystems found "in the wild" that had non-zero block 1273group checksums even though the uninit_bg/gdt_sum feature was not 1274enabled, e2fsck would issue spurious error messages. Teach 1275ext2fs_group_desc_csum_verify() to ignore the block group checksum 1276entirely if the feature flag is not set. (Addresses Debian Bug: 1277#490637) 1278 1279The blkid program will now print out a user-friendly listing of all of 1280the block devices in the system and what they contain when given the 1281-L option. (Addresses Debian Bug: #490527) 1282 1283The filefrag program now has a more accurate calculation for the 1284number of ideal extents. (Addresses Debian Bug: #458306) 1285 1286The test I/O manager is now enabled by default, but its overhead is 1287only incurred when it would be enabled via the TEST_IO_FLAGS or 1288TEST_IO_BLOCK environment variables. 1289 1290Typographical errors in various program strings and usage messages 1291have been fixed; most of these were pointed out by the e2fsprogs 1292message catalog translators. (Thanks, translators!) 1293 1294Update and clarified various man pages, as well as some typographical 1295errors in the libext2fs texinfo file. 1296 1297Fixed various Debian packaging issues --- see debian/changelog for 1298details. 1299 1300Add Indonesian and update French, Polish, Dutch, German, Sweedish, 1301Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697, 1302#401092) 1303 1304Programmer's Notes 1305------------------ 1306 1307Fix portability problem with the badblocks group; for systems that 1308don't have nanosleep(), try using usleep() instead. 1309 1310The "make check" target in the e2fsck directory now sets 1311LD_LIBRARY_PATH before running the various e2fsck internal library 1312regression tests. 1313 1314The crc32 regression test in the e2fsck library is now portable to 1315greater varienty of environments, including big-endian systems and 1316when cross-building e2fsprogs for embedded systems. (Addresses 1317Sourceforge Bug: #2019287) 1318 1319The ext2fs_extent_set_bmap() had some bugs when setting the first 1320block in a file, or when replacing a single block extent. Those cases 1321fortunately were came up relatively rarely when e2fsck was checking 1322files, but caused some problems when resize2fs was shrinking 1323extent-based files. 1324 1325Fix a potential core-dumping bug in libe2p's iterate_on_dir() 1326function. 1327 1328Various ext2fs library functions --- ext2fs_block_iterate2(), 1329ext2fs_initialize() and ext2fs_extent_open() --- now correctly free 1330allocated memory to avoid memory leaks in all of their error return 1331paths. 1332 1333Ext2ed was failing to build because masix support had been removed in 1334the rest of e2fsprogs, so ext2ed no longer has masix support, either. 1335 1336The configure script now respects the LDFLAGS environment variable if 1337it is set when configure is called. (Addresses Sourceforge Feature 1338Request: #1937287) 1339 1340Libuuid is now more portable to the Windows platform. (Addresses 1341Sourceforge Feature Request: #1937287) 1342 1343The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of 1344bare echo commands so that configure flags such as --quiet work 1345correctly. (Addresses Sourceforge Patches: #2058794) 1346 1347A few uses of sprintf have been removed from the ext2fs library to 1348make life easier for bootloaders with a limited libc environment. 1349(Addresses Sourceforge Bug: #2049120) 1350 1351The ext2fs_read_inode() checks the validity of the inode number passed 1352to it earlier, to avoid doing some needless work when it would fail 1353anyway. 1354 1355The ext2fs_open() checks the validity of the blocksize parameter 1356passed to it earlier, to avoid doing some needless work when it would 1357fail anyway. 1358 1359Disable a very annoying automatic "%.sh -> %" GNU make rule in the 1360top-level Makefile. That automatic rule is used to better support 1361SCCS, but it caused problems for a particular niche distribution which 1362likes to use configure.sh files to store the configure options used to 1363build a package. Unfortuntaely GNU make will use the configure.sh to 1364replace the configure script, resulting in a self-inflicted fork bomb 1365leading to an out-of-memory crash. 1366 1367To support old GNU C compilers don't use C99/C++ comments, but only 1368K&R style comments, and don't try to use __builtin_expect if __GNUC__ 1369is less than 3. (__builtin_expect is only supported for gcc versions 13702.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since 1371this is an optimization, we only try to use __builtin_expect for gcc 3 1372and up.) 1373 1374In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of 1375__LITTLE_ENDIAN, which are only defined by glibc's header files and 1376hence isn't portable. 1377 1378For the convenience for some distributions that need a static tune2fs, 1379the Makefile for misc/ now has a tune2fs.static target. 1380 1381The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND 1382for extent-based files 1383 1384The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based 1385files. 1386 1387All source files no longer have any trailing white space. 1388 1389The io_channel_read_blk64() and io_channel_write_blk64() functions are 1390now functions instead of C preprocessor macros to provide better 1391forward compatibility. 1392 1393The e2fpsrogs translation template now expands the @x abbrevation. 1394 1395Various namespace leackages in libblkid, libe2p, and libext2fs have 1396been fixed. 1397 1398Fix a parallel build problem in e2fsprogs. 1399 1400E2fsprogs is now more portable to Solaris. 1401 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's 1402 are always present. 1403 * Scripts do not assume that /bin/true is always in /bin 1404 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it. 1405 * Flush stdio handles before calling setbuf(), since Solaris will 1406 discard any pending output to the stream. 1407 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very 1408 picky about which C compiler can beused for SUSv3 conformance. 1409 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500), 1410 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600). 1411 Since we need some SUSv3 functions, consistently use SUSv3 so 1412 that e2fsprogs will build on Solaris using c99. 1413 * Solaris C99 does not support varargs C preprocessor macros 1414 * Solaris header files pollute the C namespace if in/netinet.h 1415 is included, which conflicts with e2fsprogs' use of the kmem_cache_t 1416 typedef. 1417 * Solaris ships with a pathetically ancient shell in /bin/sh so we 1418 avoid the use of various more avanced shell constructs such as $(). 1419 1420The "make rpm" command will now take some extra configure optiosn from 1421the build environment without needing to patch the source tree. 1422 1423The ext2fs_add_dir_block() function will now grow the dblist more 1424aggressively as an optimization to avoid copying the array too often. 1425 1426The e2fsck_write_bitmaps() will write the block and inode bitmaps 1427together instead of in two passes. 1428 1429 1430E2fsprogs 1.41 (July 10, 2008) 1431============================== 1432 1433Add support for ext4 filesystem features, in particular extents, 1434uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add 1435support for checking journal checksums. Debugfs will print new 1436superblock and inode fields that were defined for ext4. For example, 1437the nanosecond and i_version fields of an inode, and the 1438s_min_extra_isize and s_wanted_extra_isize fields from the superblock. 1439Note: Resize2fs doesn't currently support the combination of flex_bg 1440and !resize_inode. (Addresses Debian Bug: #388452, #425477) 1441 1442Tune2fs can support migrating a filesystem from using 128 byte inodes 1443to 256 byte inodes, so it can take advantage of the full features of 1444ext4. 1445 1446Add support for "undo" support. E2fsck and mke2fs can optionally 1447record an undo log which can replayed by the program e2undo. 1448 1449E2fsck could damage a filesystem by trying to relocate inode tables 1450due to corrupted block group descriptors, where the attempted inode 1451table relocation would do far more harm than good. E2fsck has been 1452fixed to detect this these sorts of corrupted block group descriptors 1453much earlier in e2fsck processing, so it can try to use the backup 1454superblock and block group descriptors first. This should be a much 1455better strategy for recovering these types of corrupted filesystems. 1456(Addresses Sourceforge Bug: #1840291) 1457 1458E2fsck will display a more understandable message when the last check 1459field in the superblock is in the future.

Fix a bug which could cause a 1479core dump while garbage collecting the blkid cache, and assure that 1480blkid_find_dev_with_tag() never returns a non-existent device. Also, 1481if a filesystem is found at a new /dev location, eliminate any 1482duplicate stale entries which can not be verified. 1483(Addresses Debian Bugs: #487758, #487783) 1484 1485Add more paranoid checks for LVM volumes and swap partitions in 1486blkid's probe function, to reduce the chances of false positives. 1487 1488The mke2fs program now has a much more sophisticated system for 1489controlling configuration parameters of a newly created filesystem 1490based on a split filesystem and usage type system. The -t option to 1491mke2fs was a deprecated alias to -c; it now specifies a filesystem 1492type (ext2, ext3, ext4, etc.), while the -T option can now be a comma 1493separated usage list. The filesystem type information and type 1494information is used to extract configuration parameters from the 1495/etc/mke2fs.conf file. 1496 1497The mke2fs program will no longer complain and request the -f option 1498when the user tries to create a filesystem with greater than 2**31 1499blocks. 1500 1501When creating a filesystem for the GNU Hurd use a fs-type of Hurd and 1502adjust the mke2fs.conf file so filesystems for the Hurd are created 1503with a blocksize of 4096 and inode size of 128, which is all it knows 1504how to handle.

Fortunately, it is highly, highly unlikely for e2fsck 1636metadata to begin with those fatal 4 byte sequence, and unless 1637data=ordered mode is in use, data blocks are never journaled. 1638 1639Updated German, Dutch, Sweedish, and Vietnamese translations. 1640 1641Programmer's notes: 1642------------------- 1643 1644Fixed various Debian packaging issues --- see debian/changelog for 1645details. 1646 1647Remove default sizes of types when cross compiling, since autoconf 16482.50 can figure this out automatically now. 1649 1650 1651E2fsprogs 1.40.9 (April 27, 2008) 1652================================= 1653 1654SuSE's security team audited uuidd and came up with a few minor 1655issues. None of them are serious given that uuidd runs setuid as a 1656unprivileged user which has no special access other than libuuid 1657directory, but it's good to get them fixed. 1658 1659One additional fix in ext2fs_swap_inode_full() needed for resize2fs to 1660work correctly with in-inode extended attributes. 1661 1662Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese 1663translations. 1664 1665Debugfs will avoid using a pager if the standard output is not a tty. 1666 1667Fix debugfs and tune2fs to correctly handle daylight savings time when 1668parsing a time string. 1669 1670Fixed spelling mistakes, typos, and otherwise clarified man pages. 1671 1672Fix fsck completion bars when multiple filesystems were being checked 1673in parallel.

If 1727the size is larger than the number of blocks found in the inode, don't 1728try to allocate extra empty blocks at the end of the directory to make 1729up the difference; there's no point to doing that. In addition, if 1730the size is not a multiple of a blocksize, always fix it. 1731 1732E2fsck handled a pass 2 "should never happen error" by not giving 1733enough information and then core dumping. Unfortunately, it was all 1734too easy to trigger the "should never happen" situation if a 1735directory's inode size was not correct. This has been fixed, but 1736e2fsck has also been taught how to handle this situation more 1737gracefully, by simply removing the inode hash tree information, so 1738that it can be rebuilt again after e2fsck's pass 3. (Addresses 1739Launchpad Bug: #129395) 1740 1741Resize2fs had a bug resizing large inodes with extended attributes 1742that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed 1743completely on big-endian systems such as PowerPC. The bug should be 1744completely fixed now. Yay for regression test suites.

There are very good reasons for wanting to 1780disable sparse_super; users who wants to turn off sparse_super can use 1781debugfs.

Having the kernel set features 1946automagically behind the user's back is a bad idea, and we should try 1947to break the kernel of this habit, especially for the newer ext4 1948feature flags. But for now, we will try to avoid needless full checks 1949which can annoy users who are doing fresh installs. 1950 1951Add support in tune2fs and mke2fs for making a filesystem as being "ok 1952to be used with test kernel code". This will be needed for using test 1953filesystems with the latest ext4 kernel code. 1954 1955Change e2fsck -fD so that it sorts non-htree directories by inode 1956numbers instead of by name, since that optimizes performances much 1957more significantly.

We 2153still had an issue when trying to figure out whether we need to 2154byte-swap fast symlinks that contained extended attributes. 2155 2156Fixed spelling mistakes, typos, and otherwise clarified man pages. 2157(Addresses SourceForge Bug #1821333.) 2158 2159 2160Programmer's Notes: 2161------------------- 2162 2163Fix mke2fs tests to avoid needing any significant ^M (CR) characters 2164 2165Add "make check" to the RPM spec file 2166 2167Fix "make install" and 'make unstall" in misc/Makefile.in so that it 2168works correctly when the prefix is not the root directory. 2169 2170Fix the resize2fs tests, r_move_itable and r_resize_inode, so they 2171clena up after themselves by deleting the test.img temporary file 2172after completing the test. 2173 2174Fixed a corner case bug ext2fs_unlink() when trying to delete the 2175first directory entry in a directory block and the last directory 2176entry in the previous directory block is not in use. Fortunately 2177ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in 2178places where it is extremely unlikely to run into this corner case. 2179 2180Fix missing dependency which would cuase parallel builds to fail. 2181(Addresses Sourceforge Bug #1842331.) 2182 2183Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c 2184calling open(O_CREATE) with a missing mode parameter. 2185 2186Fix the test_ss.c in lib/ss so it can be used as an example 2187application program for the library as well as a regression test 2188suite. 2189 2190Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes 2191are properly passed back up through the call stack. 2192 2193E2fsprogs 1.40.2 (July 12, 2007) 2194================================ 2195 2196A recent change to e2fsck_add_dir_info() to use tdb files to check 2197filesystems with a very large number of filesystems had a typo which 2198caused us to resize the wrong data structure. This would cause a 2199array overrun leading to malloc pointer corruptions and segfaults. 2200Since we normally can very accurately predict how big the the dirinfo 2201array needs to be, this bug only got triggered on very badly corrupted 2202filesystems. 2203 2204Fix a bug in e2fsck which caused it to incorrectly salvange 2205directories when the last entry's rec_len is bogusly too big. This 2206resulted in a nonsense filesystem corruption to be reported, and 2207required a second run of e2fsck to fully fix up the directory. 2208 2209Update tune2fs man page to include more discussion of reserved blocks 2210(Addresses Launchpad bug #47817) 2211 2212Update Turkish, Polish, Dutch, and Vietnamese PO files from the 2213Translation Project 2214 2215 2216E2fsprogs 1.40.1 (July 7, 2007) 2217=============================== 2218 2219Fix bug which could cause libblkid to loop forever. When revalidating 2220a partition where there is obsolete information in /etc/blkid.tab, we 2221end up freeing a the type tag without clearing dev->bid_type, causing 2222blkid_verify() to loop forever. (Addresses Debian Bug: #432052) 2223 2224The Turkish translation has a bug in it where it has the translation 2225of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at 2226@E, recursively, forever, until the stack fills up and e2fsck core 2227dumps. We fix this by making e2fsck stop @-expansions after a 2228recursive depth of 10, which is far more than we need. 2229(Addresses Sourceforge Bug: #1646081) 2230 2231Compile the default mke2fs.conf into mke2fs program. People are 2232getting surprised by mke2fs creating filesystems with different 2233defaults than earlier versions of mke2fs if mke2fs.conf is not 2234present. So we now create a built in version of mke2fs.conf file 2235which is used by mke2fs if the /etc/mke2fs.conf is not present. 2236(Addresses SourceforgeBug: #1745818) 2237 2238Improve the config/parse_types.sh helper script. Fix a potential 2239security problem if e2fsprogs is built as root (as Gentoo does!). In 2240addition fix the script and how it is called from the configure script 2241so that it does the right thing when cross-compiling. (Fixes Gentoo 2242bug: #146903) 2243 2244Update Vietnamese, French, and Dutch PO files from the Translation 2245Project. Also created a new e2fsprogs.pot file for translator. 2246 2247Fix bogus strip permission errors when building under Debian. When 2248building the e2fsprogs dpkg's, the dh_strip command emits a large 2249number of error messages caused by the permissions not being right. 2250So run dh_fixperms before running dh_strip. 2251 2252Programmer's Notes: 2253------------------- 2254 2255Add new function: profile_set_default(). This function sets the value 2256of the pseudo file "<default>". If the file "<default>" had 2257previously been passed to profile_init(), then def_string parameter 2258will be parsed and used as the profile information for the "<default>" 2259file. 2260 2261Fix mk_cmds's error reporting so that it is unambiguous that it is the 2262mk_cmds script which is generating the error. (Obviates Gentoo patch: 2263e2fsprogs-1.32-mk_cmds-cosmetic.patch) 2264 2265Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high 2266priority" environment variable that overrides all others, where as 2267LANG is the lowest priorty environment variable. If LC_ALL is set, it 2268doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and 2269the all the rest are set. This will assure that the locale when 2270running the test suites is the "C" locale.

Fortunately bid_type isn't used much, and bid_label 2284and bid_uuid is only used by debugging code, so the impact of this bug 2285was very minor. 2286 2287Mke2fs will now store the RAID stride value when a filesystem is 2288created with a requested RAID stride, and then use it automatically in 2289resize2fs. 2290 2291Mke2fs has a sanity check added to make sure (inode_size * num_inodes) 2292isn't too big. In some cases Lustre users have tried specifying an 2293inode size of 4096 bytes, while keeping an inode ratio of one inode 2294per 4096 bytes. 2295 2296Improve sanity check in e2fsck's algorithm for finding a backup 2297superblock, so that it won't accidentally find a superblock that was 2298located in the journal, and then later reject it as being not a valid 2299backup superblock. 2300 2301Fix e2fsck get_size logic so that it will work with the Linux floppy 2302driver. The Linux floppy driver is a bit different from the other 2303block device drivers, in that if the device has been opened with 2304O_EXCL, it disallows another open(), even if the second open() does 2305not have the O_EXCL flag.

The original code only checked the direct blocks to 2332make sure the journal inode was sane. Unfortunately, if some or all 2333of the indirect or doubly indirect blocks were corrupted, this would 2334not be caught. 2335 2336Add support in blkid to detect LUKS encrypted partitions. 2337 2338Add extra sanity checks for extended attributes in the case where the 2339size is zero but the offset is very large. 2340 2341Fix byte-swapping issues for large inodes in ext2fs_read_inode_full() 2342and ext2fs_get_next_inode_full(). 2343 2344Clarify the copyright licenses used by the various libraries in 2345the top-level COPYING file (Red Hat Bugzilla: 166058) 2346 2347Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. 2348 2349Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. 2350 2351Remove check in e2fsck which requires EA's in inodes to be sorted; 2352they don't need to be sorted, and e2fsck was previously wrongly 2353clearing unsorted EA's stored in the inode structure. 2354 2355Allow mke2fs or tune2fs to create a substantially larger journal (up 2356to 10,240,000 blocks). 2357 2358Fix MD superblock detection, and make sure the correct UUID is 2359reported from the MD superblock. 2360 2361Fix a signed vs. unsigned bug in debugfs. 2362 2363Enhance debugfs's date parser so that it accepts integer values. 2364 2365Fix e2fsck's pass1c accounting so it doesn't terminate too early if a 2366file with multiply claimed blocks is hard linked. or not at all if the 2367root directory contains shared blocks 2368 2369Enhance debugfs so it can modify the block group descriptors using the 2370command set_block_group_descriptor. 2371 2372Improve e2fsck's reporting of I/O errors so it's clearer what it was 2373trying to do when an error happens 2374 2375Fix a bug in in how e2fsprogs byte swaps inodes containing fast 2376symlinks that have extended attributes.

In 2630general, only e2fsck (after the filesystem is clean), tune2fs, and 2631resize2fs should change the backup superblocks by default. Most 2632callers of ext2fs_open() should not be touching any superblock fields 2633which require the backups to be touched. 2634 2635Add new function to libext2fs, ext2fs_default_journal_size(), which 2636returns the default journal size. 2637 2638 2639E2fsprogs 1.39 (May 29, 2006) 2640============================= 2641 2642Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems 2643between 2**31 and 2**32 blocks. 2644 2645Change mke2fs to use /etc/mke2fs.conf as a configuration file to 2646configure the filesystem features, blocksize, and inode_ratio for 2647different filesystem types. 2648 2649Mke2fs will now create filesystems hash trees and on-line resizing 2650enabled by default, based on the new /etc/mke2fs.conf file. 2651 2652The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the 2653filesystem device node in exclusive mode to prevent accidents by 2654system administrators. In the case of resize2fs and mke2fs, it will 2655only use exclusive mode if the filesystem is not mounted. 2656 2657Fixed a bug in mke2fs which caused it to to fail when creating the 2658resize inode for large filesystems. (Addresses Debian Bug #346580) 2659 2660When allocating space for the RAID filesystems with the stride 2661parameter, mke2fs will now place each portion of the group's inode 2662table right up after the superblock (if present) in order to minimize 2663fragmentation of the freespace. 2664 2665Speed up mke2fs and e2fsck by writing inode and block bitmaps more 2666efficiently by writing the inode and block bitmaps in one pass, thus 2667reducing the number of disk seeks required. 2668 2669Add support for on-line resizing to resize2fs. 2670 2671Fix blkid library so that logic to determine whether or not a device's 2672cached information in /etc/blkid.tab needs to be verified or not 2673doesn't get confused by a system clock which is insane (for example, 2674if the battery is dead on a Macintosh running PPC Linux. (Addresses 2675Red Hat Bug: #182188) 2676 2677The blkid library will now store the UUID of the external journal used 2678by ext3 filesystems, so that in the future, the userspace mount binary 2679can use this to find the location of the external journal and pass 2680this information to the kernel. 2681 2682E2fsck will now consult a configuration file, /etc/e2fsck.conf to 2683control how various options should be handled. See the e2fsck.conf 2684man page for more details. (Addresses Debian Bug: #150295) 2685 2686E2fsck now prints an explanatory message when delaying a filesystem 2687check when the system is running on battery. (Addresses Debian Bug: 2688#350306) 2689 2690E2fsck will detect if the superblock's last mount field or last write 2691field is in the future, and offer to fix if so. (Addresses Debian Bug 2692#327580) These problems will be fixed automatically in preen mode 2693since Debian's boot sequence bogusly doesn't set the time correctly 2694until potentially very late in the bootup process, and this can cause 2695false positives which will cause users' systems to fail to boot. 2696(Addresses Debian Bugs #343662 and #343645) 2697 2698E2fsck now checks to see if the superblock hint for the location of 2699the external journal is incorrect, and if so, offer to update it. 2700(Addresses Debian Bug: #355644) 2701 2702Fix e2fsck from segfaulting on disconnected inodes that contain one or 2703more extended attributes. (Addresses Debian Bug: #316736, #318463) 2704 2705E2fsck will stop and print a warning if the user tries running a 2706read/write badblocks test on a read-only mounted root filesystem. 2707 2708Fix a memory leak in e2fsck's error paths. (Thanks to Michael 2709C. Thompson for pointing these out; they were originally found using 2710Coverity.) 2711 2712When resizing a file containing a filesystem, resize2fs will expand or 2713truncate a file as necessary. (Addresses Debian Bug: #271607) 2714 2715Resize2fs will now automatically determine the RAID stride parameter that 2716had been used to create the filesystem, and use that for newly created 2717block groups. The RAID stride parameter may also be manually specified 2718on the command line using the new -S option to resize2fs. 2719 2720Fix mke2fs so that it correctly creates external journals on 2721big-endian machines (such as a S/390). 2722 2723Fix a bug in the e2p library which could cause dumpe2fs to (rarely) 2724fail to print out the journal or hash seed UUID. (Thanks to Guillaume 2725Chambraud for pointing this out.) 2726 2727Dumpe2fs will now print the size of the journal (if present). 2728 2729Fix debugfs's set_inode_field command so it can properly set the frag, 2730fsize, uid_high, gid_high, and author fields in the inode instead of 2731silently failing, and so that setting the i_size actually sets i_size 2732correctly. 2733 2734Add a new debugfs command, set_current_time, which sets fs->now so 2735that regression test suites can repeatedly modify the filesystem's 2736last_write fields. 2737 2738Fix a bug in debugfs's icheck which would incorrectly report the owner 2739of an extended attribute block. 2740 2741Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a 2742print a usage message when an illegal option character is given. 2743 2744Fix debugfs's dump_unsued command on filesystems with a 64k blocksize 2745so it won't core dump. (Addresses SourceForge bug #1424311) 2746 2747Fix mklost+found so that it creates a full-sized directory on 2748filesystems with larger block sizes. 2749 2750Fix a file descriptor leak in blkid library. 2751 2752Fix a display bug in "badblocks -sv" so that the done message properly 2753clears the block number at the end of the test.

Fix some fd leaks in 2761error cases. 2762 2763Add support for device mapper library to the blkid library to ensure 2764that the "best" (i.e., leaf) device is probed by the blkid library. 2765 2766Fix the blkid library so that it notices when an ext2 filesystem is 2767upgraded to ext3. 2768 2769Improve the blkid's library VFAT/FAT detection; it now understands 2770labels stored in the root directory, and is more paranoid about 2771checking the FAT superblock values. 2772 2773Fixed a fd leak in the uuid library which was causing problems for the 2774LVM tools. (Addresses Debian Bug: #345832) 2775 2776Add support for the reiser4 and software suspend partitions to the 2777blkid library. Also add support for extract the label from iso9660 2778filesystems. 2779 2780Fix a compile_et bug which miscount the number of error messages if 2781continuations are used in the .et file. 2782 2783Add extra sanity checks to protect users from unusual cirucmstances 2784where /etc/mtab may not be sane, by checking to see if the device is 2785reported busy (works on Linux 2.6) kernels.

(Addresses 2866Sourceforge Bug #1261549) 2867 2868Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially 2869intended for testing purposes. It allows an ext2/ext3 developer to 2870create very large filesystems using sparse files where most of the 2871block groups are not initialized and so do not require much disk 2872space. Eventually it could be used as a way of speeding up mke2fs and 2873e2fsck for large filesystem, but that would be best done by adding an 2874RO_COMPAT extension to the filesystem to allow the inode table to be 2875lazily initialized on a per-block basis, instead of being entirely 2876initialized or entirely unused on a per-blockgroup basis. 2877 2878Fix backwards compatibility so e2fsprogs will better compile on Linux 28792.0.35 systems. 2880 2881Make test scripts more robust against locale-related environment variables 2882 2883Fix type warning problem with sizeof() in ext2fs_open2(). 2884 2885Fix type warning problem with time_t in debugfs. 2886 2887 2888E2fsprogs 1.38 (June 30, 2005) 2889============================== 2890 2891Fix blkid's test programs (built with "make check") compile correctly 2892even without "configure --enable-blkid-debug". 2893 2894Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict 2895type aliasing rules on newer gcc compilers.

Negative bit 2981numbers were never allowed (and didn't make any sense), so this should 2982be a safe change. This is needed to allow safe use of block numbers 2983greater than or equal to 2**31. 2984 2985The compile_et program will avoid recreating generated foo_err.c and 2986foo_err.h files if no changes are necessary.

This can take place when 3040mke2fs creates the root and lost+found directory, when e2fsck creates 3041a new root inode or a new lost+found directory, and when the user uses 3042the debugfs write, mknod, or mkdir commands. Otherwise, the newly 3043create inode could inherit garbage (or old EA information) from a 3044previously deleted inode. 3045 3046Fixed a bug in e2fsck so it would notice if a file with an extended 3047attribute block was exactly 2**32 blocks, such that i_blocks wrapped 3048to zero. 3049 3050Added support to filefrag to detect files which are using the new 3051experimental file extents format, and use the non-ext2 algorithm in 3052that case. Fixed a bug to avoid reporting a false discontinuity if 3053there is one or more unallocated blocks at the beginning of a file. 3054 3055Duplicated a check for noticing whether or not the number of blocks 3056(given a certain blocksize) is greater than 2**32 when the 3057BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This 3058allows mke2fs to automatically use a larger blocksize when creating a 3059filesystem on a very large device when run on systems that do not 3060support BLKGETSIZE64. 3061 3062Fix the I18N build which was broken in e2fsprogs 1.36 because the 3063build system had been switched to treat the .gmo files as shipped 3064files (for backwards compatibility with systems that have older GNU 3065I18N tools installed), but the gen_tarball.in script was still 3066removing the .gmo files from the official source distribution. 3067 3068Fixed various Debian packaging issues --- see debian/changelog for 3069details. (Addresses Debian Bugs ##296769, #299341) 3070 3071Programmer's notes: 3072------------------- 3073 3074Added new functions to the e2p library which convert between a string 3075and os_type: e2p_os2string() and e2p_string2os(), and used them to 3076make the generated binaries more compact. 3077 3078Fixed a compile-time error on Darwin systems. 3079 3080Cleaned up the lib/ext2fs Makefile slightly. 3081 3082 3083E2fsprogs 1.36 (February 4, 2005) 3084================================= 3085 3086All of the patches that were applied to Fedore Core 3's 3087e2fsprogs-1.35-11.2 have been integrated, although sometimes with a 3088lot of bug fixes first. Users of Fedora Core 3 are strongly 3089encouraged to upgrade to e2fsprogs 1.36 as soon as possible. 3090 3091Add support for filesystem with the online resizing via resize inode 3092feature. Fixed numerous bugs from the Fedora patches. The Fedora 3093patches also didn't bother to do any consistency checking on the 3094resize inode, or add any tests to the regression test suite. The "-R 3095resize=4g" option to mke2fs was a no-op in the Fedora patches, despite 3096being listed in mke2fs's usage message. All of these shortcomings 3097have been corrected. 3098 3099E2fsck can also also fix filesystems trashed by Fedora's resize2fs 3100program. In order to do this, the user must run the commands: 3101 3102 debugfs -w /dev/hdXXX -R "features ^resize_inode" 3103 e2fsck -f /dev/hdXXX 3104 3105Optionally, the ext2prepare command can be used to re-enable online 3106resizing after the filesystem has been fixed. 3107 3108The fsck program will now accept an optional filedescriptor argument 3109to the -C option. (The Fedora version of this patch would sometimes 3110cause fsck to ignore a parameter on fsck's command line in some rare 3111cases, sigh.) 3112 3113Make sure e2fsprogs doesn't write garbage into the reserved portion of 3114large inodes. 3115 3116Make sure resize2fs releases the blocks belonging to the old inode 3117table blocks when moving the inode table.

(Addresses Red Hat 3133Bugzilla #146284). 3134 3135Add new utility program, copy_sparse.c, which is very useful 3136for dealing with large sparse files (such as e2image files). 3137 3138Add support for jnl_blocks[] for debugfs's set_super_value. 3139 3140Fix filefrag so that it works correctly with sparse files. 3141 3142Filefrag -v will print first and last blocks. 3143 3144Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs 3145and dumpe2fs. 3146 3147Add mke2fs support so that it can support filesystems larger than 4TB 3148automatically, by retrying with a 4k blocksize if the device size is 3149too big to be expressed using a 1k blocksize. (Addresses Sourceforge 3150bug #1106631) 3151 3152Change blkid to test for NTFS first because Windows sometimes doesn't 3153clear enough of the parition to confuse the probing routines into 3154thinking the old filesystem type is still valid. (Addresses Debian 3155Bug #291990) 3156 3157Add support for swap partition label and uuid's in the blkid library. 3158 3159Add support to the blkid library to recognize Oracle ASM volumes. 3160 3161Make blkid -t display all devices that match the specified criteria, 3162not just the first one, and work more consistently when the blkid 3163cache file is not available or set to /dev/null. (Addresses Debian 3164Bug #290530 and #292425) 3165 3166Badblocks will now correctly display block numbers greater than 3167999,999,999 in its progress display. 3168 3169The tune2fs program will not allow the user from setting a ridiculous 3170number of reserved blocks which would cause e2fsck to assume the 3171superblock was corrupt. E2fsck's standards for what is a ridiculous 3172number of reserved block has also been relaxed to 50% of the blocks in 3173the filesystem. 3174 3175The blkid library will return vfat in preference to msdos, and ext3 in 3176preference to ext2 (if the journalling flag is set) so that mount will 3177do the right thing. (Addresses Debian bug #287455) 3178 3179Mke2fs will now use the -E option for extended options; the old -R 3180(raid options) option is still accepted for backwards compatibility. 3181Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) 3182 3183Mke2fs will now accept a size in megabytes, gigabytes, and other units 3184(via "32m" or "4g" on the command line) if the user finds this more 3185convenient than specifying a block count. 3186 3187Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode 3188cache conherency problem. 3189 3190Debugfs now supports a new command, set_inode_field, which allows a 3191user to manually set a specific inode field more conveniently, as well 3192as set entries in the indirect block map. 3193 3194Debugfs's set_super_value command has been enhanced so that the user 3195can set most superblock fields, including the date/time fields and 3196some of the more newsly added superblock fields. 3197 3198E2fsprogs programs now accept an offset to be passed to the file 3199specifiers, via the syntax: "/tmp/test.img?offset=1024". 3200 3201E2fsprogs programs will now accept blocksizes up to 65536; kernel 3202support on the x86 doesn't exist for now, but it can be useful on 3203other architectures with page sizes greater than 4k. There are 2.6 3204kernel patches out there which enable this, but they are of this 3205writing still experimental. 3206 3207The e2image command now takes the -s option which will scramble 3208directory entries for raw image files. 3209 3210Fix a file descriptor leak in the filefrag program. 3211 3212Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not 3213present. 3214 3215Fix bug in debugfs where kill_file would lead to errors when deleting 3216devices and symlinks. (Sourceforge Bugs #954741 and #957244) 3217 3218Fix bug in the blkid library when detecting the ocfs1 filesystem 3219 3220Remove obsolete EVMS 1.x and a.out DLL support. 3221 3222E2fsck will attempt to recover from a journal containing illegal blocks. 3223 3224Fixed two potential ordering constraint problems in e2fsck which might 3225cause the filesystem to be corrupted if e2fsck is interrupted during a 3226(extremely narrow) race window. Thanks to Junfeng Yang from the 3227Stanford Metacompilation group for pointing this out. 3228 3229Fixed bug in e2fsck where it would not accurately detect whether or 3230not the system is running on adaptor if the ACPI device representing 3231the AC adapter didn't correspond to the what was used on IBM 3232Thinkpads. 3233 3234Change e2fsck to accept directories greater than 32MB. 3235 3236Fix e2fsck so that a checkinterval of zero disables a time-based check 3237of the filesystem. 3238 3239Debugfs will check the DEBUGFS_PAGER enviroment variable in preference 3240to the PAGER environment variable. (Addresses Debian Bug #239547) 3241 3242Tune2fs will not mark rewrite the superblock if the feature bitmasks 3243are not modified. 3244 3245The debugfs program will set the filetype information when creating a 3246link. 3247 3248Add debugfs -d option to use a separate source of data blocks when 3249reading from an e2image file. 3250 3251Add e2image -I option which allows the e2image metadata to be 3252installed into a filesystem. 3253 3254Fixed bug in the badblocks program which caused "done" to always 3255appear in english even when a translation was available. (Addresses 3256Debian Bug #252836) 3257 3258The blkid program has a new option -o which controls the output format 3259of the blkid program; this is makes blkid more convenient to use in 3260shell scripts. 3261 3262Fix a minor bug in uuid library, which was not using the full 14 bits 3263of clock sequence when generating UUID's. 3264 3265Fix a Y8.8888K problem in the uuid library. 3266 3267Logsave now creates a new session id for itself to avoid getting 3268killed by init whan transitioning between init levels. 3269 3270Change the licensing of the UUID library to be the 3-clause BSD-style 3271license; this allows Apple to use the uuid library in Darwin. 3272 3273Add ocfs and ocfs2 probe support into the blkid library. 3274 3275Fix a memory and file descriptor leak in the blkid library. 3276 3277The blkid library will revalidate the device if the system time is 3278earlier than last verification time of the device, since that 3279indicates that the system time is probably nottrustworthy. 3280 3281The blkid library will override the default location of the blkid.tab 3282file by the BLKID_FILE environment variable, if it is available. 3283 3284Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. 3285 3286Add various portability fixes for lame new versions of glibc, Darwin 3287and GNU/KFreeBSD, as well as removing XSI:ism's.

In 3301particular, fixed the Debian initrd scripts. (#241183, #248050, 3302#253595, #247775) 3303 3304 3305Programmer's notes: 3306------------------- 3307 3308Fixed various gcc -Wall warnings. 3309 3310The uuid library now has new functions uuid_unparse_upper() and 3311uuid_unparse_lower() which forces the case of the hex digits to be 3312upper case, or lower case. 3313 3314The build process has been speeded up by enhancing the subst program 3315to update the modtime on the generated files even when the generated 3316file hasn't changed. 3317 3318The uuid library now uses C99 stdint.h types instead of custom types. 3319 3320Updated config.guess and config.sub with newer versions from the FSF. 3321 3322Removed out of date .cvsignore files from the source distribution. 3323 3324The ext2fs_unlink() function will return an error if both the name and 3325inode number are unspecified, to avoid doing something surprising 3326(such as unconditionally deleting the first directory entry). 3327Directory entries are now deleted by coalescing them with the previous 3328directory entry if possible, to avoid directory fragmentation. This 3329is not an issue with the e2fsprogs suite, but may be a problem for 3330some of the users of libext2fs, such as e2tools. 3331 3332Add support for version numbers of the form "1.36-rc1". 3333 3334Fix build of mke2fs.static. 3335 3336Add basic ext2fs library support for large (EA in inode) inodes. 3337 3338The test_io mechanism can now abort after n reads or writes to a 3339particular block. The block is specified by TEST_IO_BLOCK environment 3340variable, and the read/write count by the TEST_IO_READ_ABORT and 3341TEST_IO_WRITE_ABORT environment variables. The block data is now only 3342dumped if the 0x10 bit is set in TEST_IO_FLAGS. 3343 3344UUID_DEFINE() in the uuid library now creates a static variable, with 3345__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can 3346be used in header files. 3347 3348Add support for the install-strip and install-shlibs-strip targets, as 3349suggested by the GNU coding guielines. "make install" no longer 3350strips the binaries which are installed. 3351 3352Remove support for the --enable-old-bitops configure option which was 3353only for very old sparc systems. 3354 3355Remove support for --enable-clear-htree; this was only needed during 3356the early development of the htree patch. 3357 3358Use Linux-kernel-style makefile output so it is easier to see compiler 3359warnings. 3360 3361Update gettext files to version 0.14.1. 3362 3363Update to use autoconf 2.5x. 3364 3365Improved support for compiling e2fsprogs under dietlibc. 3366 3367Make e2fsprogs portable to Solaris and FreeBSD systems. 3368 3369Add blkid_verify(), blkid_get_library_version(), and 3370blkid_parse_version_string() functions to the blkid library. 3371 3372Add pkg-config files for e2fsprogs's libraries. 3373 3374Fix "make uninstall" to so that it removes everything that is installed. 3375 3376Add a configure --enable-maintainer-mode option which enables the 3377makefile rules to rebuild the configure script from configure.in, and 3378to reubuild the .gmo files in po directory. 3379 3380Drop the sparc assembly bitwise operations; it's less efficient 3381than the GCC 3.4 compile code and triggers compiler warnings on 3382sparc64.

(Addresses Debian bug #228723) 3432 3433E2fsck -c now replaces the current list of bad blocks with the ones 3434found by badblocks. 3435 3436Fix bugs in e2fsck and tune2fs which could cause a core dump if a 3437non-existent LABEL or UUID specifier is to e2fsck or tune2fs. 3438 3439Fix a potential bug in e2fsck which could cause it to core dump when 3440trying to print the location of the backup superblock. 3441 3442Protect against a potential core dump in e2fsck when printing a 3443message about backup superblocks. 3444 3445Add support for backing up the journal inode location in the 3446superblock. E2fsck will automatically save the journal information in 3447the superblock if it is not there already, and will use it if the 3448journal inode appears to be corrupted. ext2fs_add_journal_inode() 3449will also save the backup information, so that new filesystems created 3450by mke2fs and filesystems that have journals added via tune2fs will 3451also have journal location written to the superblock as well. 3452Debugfs's logdump command has been enhanced so that it can use the 3453journal information in the superblock. 3454 3455E2fsck will now update all superblocks when moving the journal inode. 3456 3457Shrink the size of the e2fsck executable by moving some initialized 3458variables to the BSS segment. 3459 3460E2fsck will avoid printing the ^A and ^B characters which bracket the 3461progress bar when stdout and stdin are a tty device instead of a pipe 3462to another program.

This is for when we try stuffing an int into void * pointer. 3533 3534Fix type-punning which can cause gcc 3.x to miscompile code by getting 3535confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), 3536and ext2fs_resize_mem() all now take a 'void *' instead of a 'void 3537**'. The EVMS code uses an ugly union approach since we don't want to 3538modify the EVMS interfaces. 3539 3540Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to 3541aid build process on systems can use invoke GNU make as "gmake". 3542 3543Added regression testing for mke2fs. 3544 3545Fixed gcc -Wall nitpicks. 3546 3547Fixed various compiler warnings. 3548 3549Add portability fixes for FreeBSD and for using fsctl under Darwin to 3550support ext2 ioctl's. 3551 3552 3553E2fsprogs 1.34 (July 25, 2003) 3554=============================== 3555 3556Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in 3557a tight loop while waiting for a child fsck to exit in some cases. 3558This burns CPU times which slows down the low-level filesystem check. 3559 3560Added code to mke2fs to assure that the default block size for a 3561filesystem is at least as big as the sector size of the device, if it 3562can be determined. 3563 3564Changed mke2fs and resize2fs to round the default size of a filesystem 3565to be an even multiple of the VM pagesize in order to avoid a Linux 3566kernel bug introduced when the storage of the buffer cache was moved 3567into the page cache. 3568 3569Mke2fs will warn the user when creating a filesystem with journaling 3570and a blocksize greater than 4096. (Addresses Debian bug #193773) 3571 3572Fixed a bug in resize2fs which caused it to fail on filesystems with a 3573non-empty bad block list. Resize2fs now discards any blocks on the 3574badblock list which are no longer part of the filesystem as the result 3575of a filesystem shrink. (Note: this means that shrinking and then 3576enlarging a filesystem is no longer a reversible operation; 3577information about bad blocks in the part of the filesystem which is to 3578be chopped off will be lost.) 3579 3580Changed resize2fs so the user can use prefixes to specify the units of 3581the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), 3582and to make the error and informational messages explicitly display 3583the blocksize used by the filesystem, in order to avoid confusion. 3584(Addresses Debian bug: #189814) 3585 3586Added a new debugfs command, dump_unused, which dumps the contents of 3587all unused blocks to stdout. (Useful as an emergency try-to-find 3588deleted data command.) 3589 3590Added a new debugfs command, imap, which prints the location of a 3591specified inode in the inode table. 3592 3593Fixed a bug in the badblocks program which caused it to use one bit of 3594randomness in its non-destructive read/write test, instead of using a 3595full 8 bits of randomness. 3596 3597Added a new option (-t) to badblocks, which allows the user to control 3598the test pattern(s) used when checking a disk. 3599 3600The blkid probe function now more correctly detects UDF filesystems. 3601 3602Fixed a bug in the blkid library which caused it to not update its 3603cache if a filesystem changes from having a label to not having a 3604label. 3605 3606Fixed a bug in the blkid library wihch could avoid an infinite loop 3607in blkid_find_dev_with_tag() if /proc is not mounted and there the 3608/etc/blkid.tab file has not yet been created. 3609 3610Fixed the badblocks program so that the destructive read/write test 3611honors the -c option, and to use O_DIRECT when possible to avoid 3612thrashing the system block buffer cache. 3613 3614Fixed various NLS issues. 3615 - Added Czech and Swedish translations 3616 - Removed testing NYC translation 3617 - Fixed NLS support for message abbrevations in e2fsck 3618 - Remove de-utf.po, since we shouldn't have two versions using different 3619 charset encodings. 3620 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to 3621 simplify the statistics reporting in e2fsck. 3622 3623Changed configure.in so that its defaults for *BSD systems no longer 3624build an fsck wrapper, and not to install in /usr/local by default. 3625 3626Fixed some minor spelling errors/typo's in e2fsck and the configure 3627script. 3628 3629Fixed various Debian packaging issues (see debian/changelog). 3630 3631Updated and clarified man pages. (Addresses Debian Bug #195616) 3632 3633Programmer's notes: 3634------------------- 3635 3636Fix gcc -Wall nitpicks. 3637 3638Updated gettext implementation used by e2fsprogs to 0.11.5, and enable 3639NLS support by default. (Added partial workaround for gettext/Darwin 3640incompatibility problems.) 3641 3642Added full MIT KRB5 and Himdall compaibility support to the com_err 3643library and the compile_et program. (Addresses Debian bug #191900) 3644 3645Added the blkid_known_fstype() function to the blkid library, which 3646returns true if it is passed a filesystem type which is recognized by 3647the blkid probing functions. 3648 3649Improved the documentation for the blkid library. 3650 3651Added the ext2fs_get_device_sectsize() function the the ext2fs library, which 3652returns the hardware sector size of a device, if it is available. 3653 3654Added a dependency in the blkid library's .so file to the uuid 3655library, since the former uses the latter. (Addresses Debian bug 3656#194094) 3657 3658Added --with-diet-libc and --disable-evms to the configure script. 3659 3660Fixed a minor memory leak in the badblocks program. 3661 3662Fixed a portability problem in tune2fs --- not all systems have strptime(). 3663 3664Fixed a portability problem in debugfs with the use of getopt() more 3665than once. Old-style BSD, new-style BSD, and Linux C libraries all do 3666things differently. 3667 3668Add support Windows support to ext2fs_get_device_size(). 3669 3670Added (normally disabled) debugging code to the Unix I/O manager which 3671causes it to disable all userspace caching if the NO_IO_CACHE is 3672defined. 3673 3674Changed the test I/O manager so it can always be linked into e2fsck, 3675mke2fs, and tune2fs if enabled via --enable-test-io-debug to the 3676configure script. The test I/O manager will only print any debugging 3677information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment 3678variables are set, which specifies which I/O operations are logged and 3679a block number to watch, respectively. The log messages are sent to 3680stderr by default, unless a filename is specified via the 3681TEST_IO_LOGFILE environment variable. 3682 3683 3684E2fsprogs 1.33 (April 21, 2003) 3685=============================== 3686 3687Added a new utility program, logsave, which captures the output of a 3688command in a log file, even if the containing directory hasn't been 3689mounted yet (in which case the it saves the output in memory until it 3690can write out the logfile). This is useful for capturing the 3691output of fsck during the boot sequence. 3692 3693Fixed some portability problems that were causing problems under 3694the Cygwin32 environment. 3695 3696Mke2fs now interprets a negative number to the -b option as a minimum 3697block size. 3698 3699Fixed a bug in mke2fs which was incorrectly checking the argument to 3700the -g option if the default block size was used. (Addresses Debian 3701bug #188319) 3702 3703Fsck now explicitly ignores tmpfs and devpts, and it will complain if 3704it can not find filesystem checkers for jfs, reseirfs, and xfs. 3705 3706E2fsck now updates the global free block and inode counters from the 3707block group specific counters quietly. This is needed for an 3708experimental patch which eliminates locking the entire filesystem when 3709allocating blocks or inodes; if the filesystem is not unmounted 3710cleanly, the global counts may not be accurate. 3711 3712Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS 37132.0 is not yet supported; this only pulled in the bug fixes: fixed 3714possible hangs caused by bugs in calling waitpid, and not setting the 3715pipe to non-blocking mode; also fixed a file descriptor leak; made 3716sure all functions call log entry/exit functions.) 3717 3718Badblocks now flushes its output file as bad blocks are discovered. 3719 3720The uuid library is now more paranoid about assuming the correctness 3721of the /dev/random device; it mixes in a stream of bytes from 3722random/srandom, just in case. 3723 3724Update Debian files to reflect the fact that I am now the Debian 3725maintainer of e2fsprogs. Other various Debian-specific packaging 3726cleanups. 3727 3728Move the source tarball generation functions from the top-level 3729makefile to the util/gen-tarball script. 3730 3731Updated the Turkish .po translation file. 3732 3733Added Heimdal and MIT krb5 extensions to the com_err library to make 3734it more compatible with com_err libraries from those distributions. 3735 3736Changed dumpe2fs to always display the superblock fields relating to 3737the journalling and/or directory indexing feature even if those 3738features are not enabled. 3739 3740Updated and clarify copyright statement vis-a-vis alpha releases of 3741e2fsprogs. 3742 3743The ss library will now try to dynamically link to the readline 3744library and use it if it is present in the system. This means that 3745the debugfs program now has line editing and history features. The 3746SS_READLINE_PATH environment variable is used to find a readline or 3747readline-compatible library. 3748 3749E2fsck now finds most duplicate filenames (all when rebuilding all 3750directories via the -D option) and offers to delete or rename 3751duplicate filenames/directory entries. (Addresses Debian Bug #176814). 3752 3753Fix bug in e2image. When writing out a raw image file, include data 3754blocks from symlinks that do not store the symlink within the inode. 3755 3756Fix bug in resize2fs which incorrectly moved the block and inode 3757bitmaps for sparse superblock filesystems and incorrectly marked 3758blocks as in use. (Addresses Debian bug #174766) 3759 3760Added a new shared library, the blkid library, which efficiently 3761allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL 3762and UUID filesystem specifiers without needing to search all of the 3763devices in the system. Instead, the device is looked up in a cache 3764file, and then verified to make sure the blkid cache is correct. 3765 3766Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for 3767the device name, using the blkid library. (Addresses Debian bugs 3768#166048, #179671) 3769 3770Fsck now supports backslash escapes in /etc/fstab so that \040 can be 3771used for spaces in device labels. 3772 3773Removed 32-bit limitations for debugfs's dump command. 3774 3775If the user specifies a large number of inodes, Mke2fs will 3776automatically adjust the number of blocks per group to find a valid 3777set of filesystem parameters. 3778 3779Add workaround to detect broken MD devices where when some of the 3780underlying devices are marked read-only, writes to the MD device are 3781silently dropped. E2fsck will detect if there is an attempt to run 3782the journal twice, and abort with an error if this is the case. 3783(Addresses IBM Bugzilla bug #1226) 3784 3785E2fsck will print an error if more than one of the -p/-a, -n or -y 3786options are specified. 3787 3788E2fsck will fix HTREE corruptions in preen mode, without stopping the 3789boot process. This is needed because the 2.4 ext2 filesystem 3790accidentally had the INDEX_FL backwards compatibility code removed. 3791 3792Mke2fs no longer creates filesystems with the dir_index flag set by 3793default; the user has to specifically request it. 3794 3795Update and clarified various man pages. (Addresses Debian bugs 3796#173612, #175233, #175113, and #170497, #185945, #188318) 3797 3798Created man page for the mk_cmds program (from the libss library). 3799 3800Programmer's notes: 3801------------------- 3802 3803Fix various gcc -Wall nits. 3804 3805Fixed a lot of portability problems that caused e2fsprogs not to build 3806successfully under Solaris and Apple/Darwin. 3807 3808Fixed a Makefile dependency to allow building e2fsprogs using parallel 3809make jobs. 3810 3811Changes to create a subset distribution which consists only of the 3812et, ss, uuid, and blkid libraries. The configure script and top-level 3813makefile were changed to support working with a subset distribution. 3814 3815Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not 3816actually used, and might people who are looking for 3817EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. 3818 3819Updated debian files to fix a number of Lintian warnings. 3820 3821Updated config.guess and config.sub with newer versions from the FSF. 3822 3823Removed unnecessary libraries from being linked into the fsck, lsattr, 3824chattr, and blkid executables. 3825 3826E2fsprogs 1.32 (Nomvember 9, 2002) 3827================================== 3828 3829Fixed a bug in the Unix I/O routines which caused needless writebacks 3830of clean blocks from the unix_io cache (they were erroneously marked 3831as being dirty, so they were getting written back to disk before 3832getting evicted from the disk cache). This was harmless, but it 3833significantly slowed down e2fsck. 3834 3835Made some other minor optimizations to the Unix I/O routines to save a 3836small amount of CPU time. 3837 3838Updated internationalization files. 3839 3840 3841E2fsprogs 1.31 (Nomvember 8, 2002) 3842================================== 3843 3844Update EVMS ext2fsim plugin with EVMS 1.2. (We still support 3845compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error 3846handling for child process that die unexpectly. Add a hack to force 3847mkfs to create filesystems that won't cause problems with hardware 3848that has 2k or 4k minimum blocksize requirements. Read from child 3849processes in non-blocking mode, so that the GUI continues to update. 3850 3851Fix e2fsck so that it returns the appropriate exit code when the root 3852filesystem has been changed, so that system's rc scripts will be told that 3853the system needs to be rebooted. 3854 3855Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag 3856was set, some of the descriptor blocks that should have been written 3857out were getting skipped. 3858 3859Changed e2fsck to force out changes to the backup copies of the 3860superblock and block group descriptors when important changes are made 3861to those data structures. 3862 3863Fix a bug where e2fsck could erroneously mark a filesystem as being 3864clean if a check of dirty filesystem is interrupted with a ^C. (Bug 3865introduced in e2fsprogs 1.28.) 3866 3867If journal debuging is enabled using --enable-jbd-debug, the debugging 3868level is now set via the E2FSCK_JBD_DEBUG environment variable. 3869 3870If byteswapping support is disabled using configure --disable-swapfs, 3871skip the tests which depend on byte-swapping, so that "make check" 3872won't bomb out. 3873 3874Lshattr will now display the indexed directory flag. Also, some of 3875the more esoteric compression flags are supressed unless compression 3876support has been enabled. 3877 3878Update man pages. 3879 3880 3881E2fsprogs 1.30 (October 31, 2002) 3882================================= 3883 3884When resizing a filesystem, and inodes need to moved, resize2fs will 3885update the inode's ctime field, and the mtime field of the containing 3886directories, so that incremental backups using dump/restore will work 3887correctly. 3888 3889In order to avoid spurious errors, e2fsck wil check the last 3890superblock write time to determine whether or not it can safely use 3891the LOW_DTIME checks to determine if there are inodes on the orphan 3892inode linked list that had somehow gotten disconnected. (Addresses 3893Sourceforge bug #620980) 3894 3895Partition in /proc/partitions that being with the string "lvm" are 3896considered real partitions even if they do not end with a number. 3897 3898Fixed a bug in the the uuid generation function, where if /dev/urandom 3899is not present, but /dev/random is, and there isn't sufficient 3900entropy, the get_random_byte function could spin a loop forever. 3901 3902E2fsck, mke2fs, etc. will now reliably notice when image files are 3903mounted using the loopback interface. (Addresses Sourceforge bug 3904#619119) 3905 3906When flushing buffers (as is done by badblocks, for example) check to 3907see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the 3908FDFLUSH ioctl which causes the MD device driver which causes confusing 3909syslog messages about obselete ioctl messages. (Addresses Sourceforge 3910bug #545832). 3911 3912Debugfs's write command now checks to see if the destination filename 3913exists before creating it. (Addresses Sourceforge bug #478195.) 3914 3915When installing man pages, search for compressed man pages using all 3916commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) 3917 3918Fixed a bug in fsck where multiple filesystems specified on the 3919command were not being checked in parallel due to a logic bug 3920introduced to support the FSCK_MAX_INST environment variable. 3921 3922We have added a new superblock field, s_mkfs_time, which indicates 3923when a filesystem was created. It is set via mke2fs, and printed out 3924by dumpe2fs, but is not actually touched by the kernel. 3925 3926Dumpe2fs has been made more robust by not aborting if there is an 3927error reading the block/inode bitmaps; instead it will still print out 3928the location of the block/inode bitmaps and inode table. 3929 3930Add support for the an alternative block group descriptor layout which 3931allows for on-line resizing without needing to prepare the filesystem 3932in advance. (This is the incomat feature flag meta_bg.) 3933 3934Add support for storing default mount options in the superblock, so 3935that the filesystem can be mounted with specific mount options without 3936needing to specify them on the mount command line or in the /etc/fstab 3937file. 3938 3939Add support for a new inode flag, which is to be used for indicating 3940the top of directory hierarchies for the Orlov block allocator. 3941 3942Fix e2fsck so that if it creates the lost+found directory, it does so 3943with the more apporpriate permissions of 0700. Also change 3944mklost+found so that it also creates the directory 0700. 3945 3946Fixed format bug in e2fsck if NLS is in use. 3947 3948Add a German translation for e2fsprogs's NLS support. 3949 3950Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at 3951the beginning of the inode table. This won't matter much, since if 3952there is a bad block at the beginning of the inode table, the root 3953directory won't be available. But at least e2fsck won't crash in this 3954case. 3955 3956Fixed endian problems in the htree code for e2fsck and debugfs. 3957 3958When byte-swapping a filesystem on a PPC architecture, byte-swap the 3959bitmaps since the historical big-endian ext2 variant had byte-swapped 3960bitmaps, and the ext2fs library assumes this. This fixes the 3961regression test suite on PPC machines. 3962 3963Fix e2image so that it handles a bad block in the inode table 3964appropriately. 3965 3966E2fsck now uses a more sophisticated algorithm to salvage corrupted 3967directories that recovers more information in the corrupted directory 3968block. 3969 3970E2fsck now performs additional consistency checks on indexed (HTREE) 3971directories. 3972 3973Fix bug where efsck might get confused about whether a completely 3974empty directory block is an empty leaf block or an interior htree 3975node. This could cause e2fsck to get confused into think that a valid 3976indexed directory was corrupted. 3977 3978E2fsck no longer creates an empty directory entry at the end of a 3979directory block when optimizing a directory. This would cause some 3980earlier versions of the dxdir kernel code to corrupt the directory 3981when attempting to split a node containing an empty directory entry. 3982 3983E2fsck could sometimes in rare circumstances leave the indexed flag 3984set after a small directory was optimized by compressing it instead of 3985indexing it. (This should never happen in real life, since 3986directories that small wouldn't have been indexed, but better safe 3987than sorry.) 3988 3989E2fsck now only updates the master superblock in all cases. This 3990slightly shortens its run time. 3991 3992Ext2ed can deal with directory entries of length 0; previously it 3993would get stuck in an infinite loop. 3994 3995Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= 3996specifiers. (Sourceforge patch #613447) 3997 3998Badblocks will now work correctly on read-only devices such as 3999CD-ROM's. (Sourceforge patch #600451) 4000 4001Updated and clarified man pages. (Addresses Debian bug #167108) 4002 4003 4004E2fsprogs 1.29 (September 24, 2002) 4005=================================== 4006 4007Fixed a bug in e2fsck which could corrupt a directory when optimizing 4008it (via the -D option) or rebuiliding the hash tree index with a 1 in 4009512 probability, due to a fence post error. 4010 4011Fixed a bug in the LVM support code which caused LABEL='xxx' not to 4012work correctly. 4013 4014Mke2fs now enables the directory indexing flag by default. (Since 4015this is a compatible feature flag, it's safe to do so.) 4016 4017Tune2fs will support setting the directory indexing feature flag. It 4018will automatically set up the default hash algorithm and hash seed 4019fields in the superblock. 4020 4021If the bone-headed user enters the root filesystem twice in 4022/etc/fstab, the -R option which skips the root filesystem will skip 4023all of them. (Addresses Debian bug #159423). Note! This is not a 4024precedent for dealing intelligently with any other kind of doubled 4025entry in /etc/fstab! 4026 4027 4028Programmer's notes: 4029------------------- 4030 4031Removed perror declaration in lib/et/internal.h. All modern systems 4032can be expected to define perror() these days. Besides, the lib/et 4033code wasn't using perror at all anyway. :-) 4034 4035 4036E2fsprogs 1.28 (August 31, 2002) 4037================================ 4038 4039Add support for the Hashed-Tree Directory Indexing to e2fsck. Support 4040for setting the htree flag is not included yet, although it can be 4041manually turned on via the debugfs program. 4042 4043Clarified e2fsck error message which is printed when it cannot find 4044sufficient contiguous block when relcating filesystem metadata. 4045 4046Added support for building an EVMS plugin module for ext2/3. This 4047module is substantially the same as the EVMS module shipping with EVMS 40481.1, with one or two bugfixes. E2fsprogs can also build this plugin 4049for use with EVMS 1.0 (which did not include the ext2 plugin module), 4050if the configure --enable-old-evms flag is given. 4051 4052Fsck will search through EVMS volumes when trying to resolve 4053filesystem specifications such as LABEL=xxx or UUID=xxx. 4054 4055Added a new utility program, /sbin/findfs, which will return 4056filesystem specifications such as LABEL=xxx or UUID=xxx, and prints 4057the device name. 4058 4059Update and clarified various man pages. (addresses Debian Bug #145044, 4060#146437, #131350, #151990, #144621, #141938) 4061 4062If there are no filesystems specified on fsck's command line, fsck now 4063treat that as if the -As options were given. Previously it would 4064simply do nothing. (Addresses Debian Bug #153102) 4065 4066Mke2fs no longer treats a failure to be able to clear the MD signature 4067at the end of the filesystem as a fatal error. (Addresses Debian Bug 4068#155007) 4069 4070The e2p library functions (which are used by lsattr and chattr) now 4071double check to make sure the file is a regular file or directory 4072before attempting to use the ext2 ioctls. Some device drivers 4073unfortunately respond to the ext2 ioctl's with unknown behaviour. 4074(Addresses Debian Bug #152029). 4075 4076The extended attribute handling has been updated to correspond with 4077the latest V2 bestbits ACL code. 4078 4079Fixed bug in e2fsck which caused it to not clear the dtime field when 4080processing truncated inodes on the orphan list. This could cause data 4081loss(!) if a filesystem is rebooted before a truncate has been 4082committed. 4083 4084E2fsck now uses red/black trees in pass1b, which removes some O(n**2) 4085algorithms. This makes e2fsck much faster in the case of severely 4086corrupted filesystems where a large number of blocks are claimed by a 4087large number of inodes. (Thanks to the 2.5 IDE device driver for 4088inspiring this work.) 4089 4090Resize2fs has been significantly sped up when shrinking and expanding 4091a filesystem by a very small number of blocks (for example, when EVMS 4092is converting a partition to be an EVMS legacy volume). 4093 4094Added a new option to e2fsck, -D, which will optimize or compress all 4095of the directories in the filesystem. 4096 4097E2fsck now catches SIGINT and SIGTERM to make sure it will can 4098properly clean up and only exit at safe points. Fsck will pass 4099SIGINT/SIGTERM to its child processes, and wait until they have all 4100exited before it exits. 4101 4102The uuid parsing code in the uuid library now properly complains when 4103an illegally formated uuid is presented to it. (Addresses Debian bug 4104#152891) 4105 4106Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 4107and 2.4.17, since the workaround can cause problems when using a 2.4 4108kernel with an old version of glibc built with the 2.2 headers. 4109 4110Fixed a bug in mke2fs where it wasn't properly clearing the initial 4111superblock used by other filesystems. (Addresses Debian bug #147256.) 4112 4113Added support for the synchronous directory feature written by Andrew 4114Morton. 4115 4116The debugfs program can delete directories using the rmdir command. 4117 4118Add support for 8k and 16k filesystems (for systems with page sizes 4119that are greater or equal to 8k or 16k, respectively). Note that 4120these filesystems can not be mounted on x86 systems, or other systems 4121with only 4k page sizes, due to limitations in the current Linux VM 4122code. 4123 4124Resize2fs requires that the filesystem state be valid and have no 4125errors; otherwise, e2fsck -f must be run first. (Previously it simply 4126required that the last fsck time be greater than the last mount time.) 4127 4128Configure now defaults the man pages directory to /usr/share/man on 4129Linux systems. 4130 4131E2fsck now offers to truncate inodes which contain too many blocks (so 4132that i_blocks would overflow. Also fixed handling of large sparse 4133files. 4134 4135E2fsck now more completely checks for symlink validity, including 4136requiring NULL termination and length checks. 4137 4138E2fsck will offer to try forcing a disk write to remap a bad block 4139after finding a read error when reading a filesystem metadata block. 4140 4141Fixed a bug in debugfs which caused the -b and -s options to crash 4142debugfs, as well as breaking the testb, setb, and clearb functions. 4143 4144Added a bmap command to debugfs which calculates the logical to 4145physical block mapping for a particular inode. 4146 4147Fixed a bug in code which checked to see if a device was mounted which 4148sometimes (rarely) failed in the case of a plain file. 4149 4150Fixed a bug in resize2fs where when it reported an error, it would 4151print a message erroneously indicating that the filesystem had been 4152resized before it aborted. 4153 4154When resizing a plain file which is smaller than the requested size, 4155resize2fs will attempt to extended the file so that programs like 4156e2fsck will not complain that the file is too small. 4157 4158Resize2fs will print the actual new size of the filesystem when it is 4159finished resizing. 4160 4161Fixed a bug in debugfs where "ls -l" would report incorrectl file type 4162information on big-endian systems. 4163 4164 4165Programmer's notes: 4166------------------- 4167 4168Fixed collisions with C++ reserved words. 4169 4170Added portability fixes for building e2fsprogs on the HURD and AIX. 4171 4172Added the ext2ed program for creation of test cases. (ext2ed has many 4173limitations and bugs which make it unsuitable for production use.) 4174 4175The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new 4176flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the 4177name_len field is byte swampped on big-endian machines, since in the 4178V2 structure, name_len is a char field which is doesn't need to be 4179byte swapped --- except if an old-style kernel had byte-swapped the 4180name_len field as part of the V1 structure. 4181 4182 4183E2fsprogs 1.27 (March 8, 2002) 4184============================== 4185 4186The warning messages for mke2fs now go to standard error. 4187 4188Fixed to make sure "make check" runs all of the test programs with 4189LD_LIBRARY_PATH set, so that we test the libraries in the build tree. 4190 4191The mke2fs program checks the boot sector for the BSD disk label, and 4192avoids erasing it if it is there. 4193 4194Fixed a bug in e2fsck which caused it to core dump if the journal 4195inode was missing when it was supposed to be there. 4196 4197E2fsck now prints ranges in pass 5 when printing deltas for the block 4198and inode bitmaps. 4199 4200Debugfs's "ls -l" command now will print out the file type information 4201in the directory entry. 4202 4203Create man pages and hard links for fsck.ext3 and mkfs.ext3. If 4204mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. 4205 4206Debugfs can now examine the experimental directory indexing 4207information. 4208 4209Fixed bug in debugfs which caused it to core dump if modify_inode is 4210called without an open filesystem. 4211 4212The debugfs lsdel command now runs its output through a pager first. 4213 4214When installing manual pages, remove the compressed manual pages first. 4215 4216Synchronized with Debian's packaging information for e2fsprogs-1.26-1. 4217 4218Fix the 2.4 resource limitation workaround introduced in 1.26 which 4219actually broke things on mips32, sparc32, and Alpha platforms. 4220 4221Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made 4222(which is required by the newer libintl libraries). 4223 4224Programmer's notes: 4225------------------- 4226 4227Fixed various gcc -Wall complaints. 4228 4229Fixed a few memory leaks in the e2fsck journaling code, and in the 4230ismounted code checking for a swap device. 4231 4232Add new inode I/O abstraction interface which exports an inode as 4233an I/O object. 4234 4235Exported ext2_file_flush as a public interface. 4236 4237In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. 4238 4239Lots of small random portability fixes to make e2fsprogs build under 4240AIX --- even without the 5L compatibility toolkit, and even using the 4241uber-crippled AIX native C compiler. 4242 4243 4244E2fsprogs 1.26 (February 3, 2002) 4245================================= 4246 4247Dumpe2fs will keep going now if the bad block inode can't be read. 4248(Previously it stopped with a fatal error.) 4249 4250E2fsck will now give an opportunity to run the journal even if the 4251recovery flag is not set. This is the default behaviour if e2fsck is 4252using a backup superblock, since the needs_recovery flag will never be 4253set in the backup superblock copies. 4254 4255E2fsck now automatically finds the backup superblock/group descriptors 4256even when the primary superblock is completely destroyed for 2k and 4k 4257filesystems. (Previously it just guessed/assumed that we were dealing 4258with a 1k filesystem in that case, and users had to manually specify 4259the backup superblock number.) 4260 4261Fixed a bug in e2fsck where it dereferences a null pointer when there 4262is a problem opening a filesystem in preen mode. 4263 4264E2fsck now handles external journals correctly; previously it trashed 4265the external journal device if the journal needed to be replayed. 4266 4267Work around ulimit incompatibility problem caused by recent 2.4 4268kernels; the unix IO module will automatically try to set any resource 4269limits to be infinite on startup. 4270 4271Fixed a bug in e2fsck where it wasn't allocating a new block or inode 4272bitmap if it wasn't present and the blocksize was 2k or 4k. 4273 (Addresses Debian Bug #116975) 4274 4275E2fsck will check and fix botched ext3 V1 to V2 superblock updates by 4276clearing the new V2 fields if they do not make sense or if the ext3 4277superblock is version 1 superblock. 4278 4279E2fsck will automatically relocate the ext3 journal from a visible 4280file (i.e., /.journal) to an hidden inode if the filesystem has been 4281opened read/write. This allows the users to add a journal while the 4282filesystem is mounted, but the next time the system is rebooted, the 4283journal file will disappear. This avoids problems with backups, 4284stupid operators with superuser bits, etc. 4285 4286Fix a bug in fsck where it would not support a filesystem type of 4287"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. 4288 4289Fsck now supports fstab entries of the form "ext3,ext2". It will also 4290automatically identify reiserfs filesystems. 4291 4292The number of processes spawned by fsck can now be limited using the 4293FSCK_MAX_INST environment variable. 4294 4295Fsck now searchs the LVM proc hierarchy to find logical volumes which 4296should be searched for UUID and label information. 4297 4298Work around a bug in 2.4.10+ kernels by trying to unset the filesize 4299limit if at all possible, when opening a block device. (The filesize 4300limit shouldn't be applied against writes to a block device.) 4301 4302In mke2fs and e2fsck, specifying the -c option twice will now do 4303a read/write test on the disk. Update the man pages to encourage 4304using the -c option, and to discouraging running badblocks separately, 4305since users tend to forget to set the blocksize when running 4306badblocks. 4307 4308Mke2fs now automatically clears the immutable attribute on a 4309pre-existing .journal file left over from a previous failed attempt to 4310add a journal to an alreadyy-mounted filesystem. 4311 4312Fixed mke2fs's exit codes to consistently indicate when the mke2fs 4313operation failed. 4314 4315Mke2fs now creates the lost+found directory with permissions of 0700, 4316so that files that had previously lived in protected directory are 4317safe if they get dropped in lost+found and the system administrator 4318doesn't deal with immediately. (Addresses Debian #bug 118443) 4319 4320Mke2fs and e2fsck (and all programs that use the 4321ext2fs_check_if_mounted function) will now properly identify that a 4322device is mounted, even in cases where devfs has confused things with 4323multiple devices names with the same identity, or if a dim-witted 4324system administrator has done something stupid like creating device 4325file aliases in their home directory. Also now checks for swap devices 4326by using /proc/swaps. (Addresses Debian bug #106622) 4327 4328Added a new option (-T) to tune2fs which sets the time a filesystem 4329was last checked. 4330 4331Speed up e2image when creating sparse raw image files by optimizing 4332away excess lseek() system calls. 4333 4334Fix support of large (> 2GB) files when used as a filesystem in 4335mke2fs, tune2fs, debugfs, and findsuper. 4336 4337Debugfs's stat and icheck commands now properly deals with large (> 43382GB) files. 4339 4340Debugfs's set_super_value command now prints out the list of valid 4341superblock fields which can be set using the command. 4342 4343Debugfs's rm and kill_file command now updates the superblock free block 4344and inode counts, thus keeping the filesystem consistent. 4345 4346Debugfs's lsdel command now takes an optional argument which allows 4347the user to only see the most recently deleted files. 4348 4349A new command (undel) was added to debugfs which automates 4350undeleting a deleted inode and linking it back to a directory. 4351 4352Debugfs's ls command now takes a new option, -d, which lists 4353deleted directory entries. 4354 4355Debugfs's testb, freeb, setb, and find_free_block commands now take an 4356optional count argument. 4357 4358Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will 4359be used to signal that a particular inode should not be eligible for 4360tail-merging --- this is needed for programs like LILO. 4361 4362The findsuper (an unreleased, uninstalled utility program) has been 4363improved to add extra validity checks and to add a progress meter. 4364(It is still an unsupported program; the officially supported way to 4365recover from a trashed partition table is to use gpart; findsuper is 4366for wizards only. :-) 4367 4368Debugfs was fixed to compile with "configure --disable-swapfs". 4369 4370Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) 4371 4372Added new translation file for Turkish. 4373 4374Programmer's notes: 4375------------------- 4376 4377Fix general gcc -Wall complaints. 4378 4379E2fsprogs (mostly) works with the dietlibc. 4380 4381The programming texinfo file has been expanded to include description 4382of additional libext2fs functions. (Still not compeltely done, but a 4383lot of the more important functions have been documented.) 4384 4385Added a umask structure to struct_ext2_filsys, which currently only 4386modifies the behaviour of ext2fs_mkdir(), but if we add any file 4387creation functions to libext2fs, we should also make sure they respect 4388the umask setting. 4389 4390The build-rpm script was fixed to be a bit more safe. 4391 4392The tests' Makefile now has a way of automating test case creation 4393for e2fsck, using "make testnew". 4394 4395Created a new function, ext2fs_dir_iterate2 which passes more 4396information to the callback function (identical to the one used by 4397ext2fs_dblist_dir_iterate). The directory iterator functions take a 4398new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted 4399directory entries. If the directory entry is deleted, the callback 4400function will be called with the entry paraemter set to 4401DIRENT_DELETED_FILE. 4402 4403Added new functions, ext2fs_inode_alloc_stats and 4404ext2fs_block_alloc_stats, which takes updates block/inode allocation 4405statistics in the bitmaps, block group descriptors, and superblock 4406when inodes or blocks are allocated or deallocated. 4407 4408 4409E2fsprogs 1.25 (September 20, 2001) 4410=================================== 4411 4412This is primarily a bug-fix release; no new features were added, but 4413there are a number of embarassing bug fixes and cleanups applied. 4414 4415Fix a bug mke2fs which causes stack garbage to be written to disk when 4416zapping disk sectors. (This bug could cause mke2fs to core dump for 4417some kernels, I suspect with security enhancement patches.) 4418 4419Remove unneeded #include of <linux/config.h> which was breaking 4420building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) 4421 4422Updated tune2fs man page to reflect the fact that adding or removing a 4423journal doesn't require running e2fsck. 4424 4425Remove use of AC_REQUIRE from autoconf which had been used to prevent 4426AC_CANONICAL_HOST from being called twice; unfortunately this causes 4427recent autoconf to bomb out since they don't allow AC_REQUIRE to be 4428used outside of autoconf macros. Fortunately, it doesn't seem to be 4429necessary any more, anyway. 4430 4431E2fsck will now not fall back to an alternate superblock if the user 4432specifies the superblock location explicitly on the command-line. 4433This allows easier recovery from a situation where the primary 4434superblock and block groups are slightly corrupted, but the backup 4435superblocks are completely broken. 4436 4437Fix problem which caused compile_et and mk_cmds to blow up if 4438e2fsprogs was in a directory with a pathname that contained spaces. 4439 4440We are now more paranoid about checking the entry in /etc/mtab to make 4441sure the filesystem is really mounted, since some broken distributions 4442(read: Slackware) don't initialize /etc/mtab before checking non-root 4443filesystems. (Slackware also doesn't check the root filesystem 4444separately, and reboot if the root filesystem had changes applied to 4445it, which is dangerous and broken, but there's nothing I can do about 4446that.) 4447 4448Make UUID library C++ friendly by adding appropriate extern "C" 4449declarations and using const in the function declarations. 4450 4451Fix up the com_err texinfo file so that it can product a valid info 4452file (previously, it could only be used to generate paper 4453documentation using texinfo.tex). 4454 4455 4456E2fsprogs 1.24a (September 2, 2001) 4457=================================== 4458 4459Fix brown-paper bug in mke2fs which caused it to segfault when 4460printing the version string. 4461 4462 4463E2fsprogs 1.24 (August 30, 2001) 4464================================ 4465 4466Revert the BLKGETSIZE64 support, since for some distributions, this 4467ioctl has been used by an unofficial kernel patch to update the last 4468sector on the disk, and this was causing disk corruption problems as a 4469result. 4470 4471Mke2fs is now more careful about zapping swap space signatures and 4472other filesystem/raid superblock magic values so that programs like 4473mount who try to use hueristics to determine the filesystem type of a 4474partition are less likely to be confused. 4475 4476E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a 4477regular file (since Andreas Dilger's on-line resizing tools will set 4478its mode bits). 4479 4480Fixed some minor texinfo, man pages nits for spelling errors, 4481texinfo warnings, etc. (Addresses Debian bug #110621.) 4482 4483E2fsprogs program no longer print the filesystem version number 4484(i.e. 0.5b), since it only confuses people and doesn't serve any real 4485purpose. 4486 4487E2fsck will once again compile under libc5, since it will supply its 4488own version of strnlen if necesssary. 4489 4490mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers 4491when specifying the external journal device. tune2fs will also search 4492devices looking for the externla journal debice when removing. 4493 4494E2fsprogs 1.23 (August 15, 2001) 4495================================ 4496 4497Add initial support for extended attributes (EA); e2fsck will 4498correctly handle a filesystem with EA's and check the EA blocks for 4499corruptions. 4500 4501E2fsck's symlink sanity checking has been cleaned up. It now checks 4502the i_size value of fast symlinks, and checks for immutable flags 4503being set of symlinks, etc. 4504 4505E2fsck now offers to clear inodes which are special files that have a 4506non-zero i_blocks or i_size field. (The i_size field check was in the 4507previous version of the code, but due to a bug it didn't offer to 4508clear the inode unless i_size and i_size_high were both non-zero.) 4509 4510E2image can now create "raw" image files, which only contain the 4511filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, 4512debugfs, etc., can be run directly on the raw image file. 4513 4514Add support for the 64-bit block device patches. 4515 4516Fixed bugs in creating external journals with a 1k blocksize. 4517 4518Add initial support for external journals (so long as the external 4519journal only supports a single filesystem) in e2fsck. 4520 4521Remove requirement for needing to run fsck on a filesystem after 4522removing a journal (either internal or external). 4523 4524The man pages now document how to create and manage external journals. 4525 4526Speed up the check of an ext3 filesystems by avoiding a needless flush 4527of all of the superblock and block group descriptors. 4528 4529Speed up creating an internal journal using tune2fs in the case where 4530the filesystem has a lot blocks already allocated. 4531 4532Tune2fs has been fixed to make sure that only error messages go to 4533stderr, and normal message go to stdout. (Addresses Debian bug #108555) 4534 4535Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will 4536now not set the sparse_super feature. (Addresses Debian bug #108165) 4537 4538Add support in fsck for the filesystem type "auto". 4539 4540Fsck -A will not try to interpret device names for filesystems which 4541have a pass number is 0. (Addresses Debian bug #106696). 4542 4543Fsck prints a warning message if now valid filesystems are passed to 4544it. (Addresses Debian Bug #107458.) 4545 4546E2fsck now gives an explicit warning if there filesystem still has 4547errors at the end of the run. (Addresses Debian bug #104502) 4548 4549E2fsck will set the EXT2_ERROR_FS flag if the journal superblock 4550reflects an error. E2fsck will also not run the orphan list if the 4551filesystem contains errors, since the orphan list might be corrupted. 4552 4553E2fsck now prints the number of large files when given the -v option. 4554 4555Fixed minor memory leaks in e2fsck. 4556 4557Some minor man pages updates. (Addresses Debian bug #30833, #108174) 4558 4559 4560E2fsprogs 1.22 (June 22, 2001) 4561============================== 4562 4563Fixed a bug in e2fsck's handling of orphan inodes which are special 4564files (i.e., block/character device files, named FIFO's, etc.). 4565 4566Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused 4567tune2fs to fail at adding a journal to a mounted filesystem. 4568 4569Fixed a few big-endian bugs in e2fsprogs 4570 * The directory block functions were accidentally reporting 4571 some directories as corrupted when they weren't. 4572 * If e2fsprogs is compiled --disable-swapfs, the C language 4573 equivalents weren't being included for big-endian platforms. 4574 (Fixes Debian bug #101686). 4575 4576Fixed a Hurd compilation problem. (Addresses Debian bug #101361) 4577 4578Programmer's notes: 4579------------------- 4580 4581Use platform independent method of defining the BLKFLSBUF and FDFLUSH 4582ioctls, and allow them to be defined for non-i386 platforms. 4583 4584The uuid.h header file is now protected against multiple inclusions. 4585 4586E2fsprogs is now being developed using BitKeeper. Changed the test 4587scripts to deal with BK's stripping CR characgters from text files, 4588and changed the top-level Makefile.in to avoid including BitKeeper 4589files when generating the source tarball. 4590 4591 4592E2fsprogs 1.21 (June 15, 2001) 4593============================== 4594 4595Added new configure flags which allow a subset e2fsprogs to be built; 4596this is most useful for boot floopies, since the resulting shared 4597libraries and programs are slimmed down by removing features that 4598aren't necessary for a boot floppy. The new flags that were added 4599are: --disable-swapfs, which removes support for byte swapping old 4600legacy PPC/68k filesystems, --disable-debugfs, which removes support 4601for debugfs from the libext2fs library, --disable-imager, which 4602removes support for the e2image program, and --disable-resizer, which 4603removes support for resize2fs. 4604 4605E2fsck now prints the number of mounts or days elapsed since the last 4606check when e2fsck is forced to check an otherwise clean filesystem. 4607 4608Tune2fs now prints an informative message about how often a filesystem 4609will be checked when adding a journal to the filesystem, to remind the 4610user that he/she may want to adjust those parameters using tune2fs 4611-c/-i. 4612 4613Worked around hurd brain-damage which causes e2fsck to sometimes 4614believe a filesystem is the root filesystem based on device numbers 4615(since Hurd doesn't have dev_t's, which is arguably a POSIX.1 4616violation). 4617 4618Fixed a bug introduced in 1.20 which caused e2fsck to abort with an 4619erroneous error with the -F option was specified. 4620 4621Fixed a ext3 recovery bug in the revoke handling; synchronized with 4622ext3 0.7a. 4623 4624Fixed two bugs in e2fsck's handling of dup block handling, dealing 4625with relatively uncommon edge cases: a directory with an indirect 4626block which is claimed by another file, and when the last inode in the 4627filesystem has blocks claimed by another file. 4628 4629E2fsck now checks to see if the i_size field of a fast symlink is too 4630big, and offers to clear the symlink if so. 4631 4632E2fsck now checks to see if i_size_high of special files is non-zero, 4633and offers to clear i_size_high. 4634 4635Fix e2fsck's handling of incompatible journal flags so that the user 4636has chance to abort, and then has the option to clear out the journal 4637entirely. (Addresses Debian bug #98527.) 4638 4639Fixed a bug in fsck which could cause it to core dump if a mix of 4640standard and non-standard device names are used in /etc/fstab. 4641(Debian bug #100559) 4642 4643Fixed a bug in debugfs which caused read errors when copying a file to 4644not be noticed. 4645 4646The debugfs set_super_value command can now modify the s_lastcheck field. 4647 4648Fixed a bug in lsattr and chattr which was accidentally introduced in 46491.20 to support > 2GB files; both lsattr and chattr wasn't reading 4650directories correctly because the change modified the layout of struct 4651dirent to be incompatible with the libe2p shared library. 4652 4653Cleaned up the mke2fs manual page and included a discussion about why 4654it's good to periodically check the filesystem even when journaling is 4655enabled. 4656 4657Programmer's notes: 4658------------------- 4659 4660Fix general gcc -Wall complaints. 4661 4662The types needed by the ext2 header files are now provided by 4663lib/ext2fs/ext2_types.h, instead of include/asm/types.h. 4664 4665Integers are now preferred to longs when trying to find a 32-bit type 4666in ext2_types.h. Also, if linux/types.h has already been defined, 4667don't try to redefine the types. 4668 4669Fixed make depend script so that it automatically corrects the 4670pathname cleanups performed by make -M, so I don't have to fix them up 4671by hand. 4672 4673Fixed the d_loaddump test case to be more robust, and not depend on 4674bash'isms. 4675 4676Removed debugfs's dependence on pread(), which was accidentally 4677intrudced in e2fsprogs 1.20 4678 4679Fixed a performance bug in the libext2fs's icount routine; the size 4680estimate of the icount array was incorrectly being calculated. 4681 4682Removed use of the badblocks compatibility functions in the e2fsprogs 4683programs. 4684 4685Added paranoia code which protects against strange cases where /etc 4686isn't on the root filesystem, or if /etc/mtab doesn't exist. 4687 4688The header file ext2_types.h is now installed. 4689 4690Autoconf is used to determine when we are on big-endian machines, 4691instead of doing run-time tests, to save a few bytes of code. 4692 4693The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap 4694functions are no longer inline functions, which saves space and 4695doesn't really cost any real performance. 4696 4697The ext2fs library no longer depends on the e2p library. (What need 4698there was of it --- namely, fsetflags, was coded in-line). 4699 4700Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even 4701when the user is stupid and tries compiling the package using "make 4702install" as root. 4703 4704Miscellaneous code cleanups: 4705 * Added missing files from Makefile.in's SRCS file, so that 4706 their dependencies would be properly calculated. 4707 * Removed redundant code 4708 * Fixed comments in code 4709 * Removed no-longer unneeded argsused #pragma. 4710 4711 4712E2fsprogs 1.20 (May 20, 2001) 4713============================= 4714 4715Add support for replaying the ext3 journal purely in user mode, 4716including handling the orphaned inode list. Used code contributed by 4717Andreas Dilger, with bug fixes and the orphaned inode handling done 4718by Theodore Ts'o. 4719 4720The mke2fs and tune2fs programs can create or modify a filesystem to 4721include an ext3 journal. Tune2fs also can be used to remove an ext3 4722journal from a filesystem. 4723 4724E2fsck will now check for the existence of a linked list of orphan 4725inodes in the superblock, and clear those inodes before starting the 4726rest of the filesystem check (but after the journal playback). 4727 4728E2fsck now validates the file descriptor passed to the -C option, 4729which saves against the completion bar getting written to an 4730unexpected location, such as the disk being checked. (Debian 4731bug/wishlist #55220) 4732 4733E2fsck will now bump the filesystem revision number from zero to one 4734if any of the compatibility bits are set. 4735 4736Fixed a bug where a badly corrupted directory on a big endian system 4737could cause e2fsck to die with a bus error. The 4738ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in 4739the ext2 library now does alignment sanity checks on the rec_len field 4740of the directory entry before using it. 4741 4742The ext2 library has been enhanced to make tune2fs safe to run on 4743mounted filesystems. (Users could usually get away with using tune2fs 4744on mounted filesystems before, but with the advent of ext3 and 4745journaling, it became important to make tune2fs was *really* safe for 4746use even when the filesystem being modified is mounted.) E2label is 4747now implemented by tune2fs using an argv[0] dispatch, so that e2label 4748is also now safe for use on mounted filesystems. 4749 4750Added a new program, e2image, which creates a backup of critical ext2 4751filesystem data structures. The generated image file can be examined 4752using dumpe2fs and debugfs. In the future, e2fsck will be able to use 4753the image file to help recover very badly damaged filesystems. 4754 4755Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files 4756no longer cause e2fsck to bomb out. Also treat files > 2GB as being 4757large file when deciding whether or not the filesystem has large files. 4758 4759Fixed lsattr and chattr so that they work correctly on large files. 4760(Fixes Debian bug #72690.) 4761 4762Removed limitation in get_device_size() which imposed a one terrabyte 4763filesystem limitation. (Most 2.2 kernels still have a signed int 4764problem which cause 1 TB block device limitation. Fortunately, the 4765kernel patches to fix this are much easier than fixing the 2TB 4766limitation in the kernel. :-) 4767 4768A max_mount_count of zero is now treated as if no mount count were 4769set. (Previously, no mount count was indicated by using -1, and a 4770mount count of zero caused e2fsck to always be run.) 4771 4772Mke2fs supports two new filesystem types largefile and largefile4. 4773 4774Mke2fs now adds some randomness in s_max_mount_count so that multiple 4775filesystems won't be all checked at the same time under normal 4776operations. 4777 4778Fixed bug in the progress bar printing code which could cause e2fsck 4779to core dump on an illegal filesystem. 4780 4781Fixed bug in fsck which could allow more than one instance of e2fsck 4782to be printing a progress bar. (Debian bug #65267) 4783 4784Fsck using a UUID or a LABEL specifier will work even if devfs is 4785compiled into the kernel and not mounted. If the pathnames in 4786/proc/partitions are incorrect, fsck will search /dev for the correct 4787device (using the new ext2fs_find_block_device library function). 4788Fsck now also checks the RAID devices first so that they are properly 4789found when they are in use. Support has also been added to support 4790additional IDE disks and the DAC 960 device names. (Debian bug #94159) 4791 4792Fixed a bug in fsck which caused it not deal properly with 16 4793byte long filesystem labels. 4794 4795Fsck's -t option has been made a lot more flexible. The semantics for 4796what happens if a comma-separated list to fsck has been regularized, 4797and it is now possible to filter what filesystems will get checked 4798based what is in the filesystem's fstab entry's option field. (Debian 4799bug #89483.) 4800 4801The dumpe2fs program can now print out the group description 4802information in hex, and also prints the location of the superblock and 4803block group descriptor for those block groups that have them. 4804 4805Mke2fs now clears the ext2 superblock before it starts creating a 4806filesystem, so that the superblock magic number is only written if the 4807filesystem creation process successfully completes. 4808 4809The debugfs program's stat command now pretty-prints the blocks used 4810by an inode so that it's more compact and informative. 4811 4812The debugfs stats command now uses the same libe2p code (which is used 4813by dumpe2fs) to print the superblock header information. This is more 4814complete, and it avoids a bit of code duplication. 4815 4816Added a new debugfs command, set_super_value (ssv) which allows the 4817user to set arbitrary superblock fields. 4818 4819Debugfs was extended to support inode numbers in hex (by prefixing 4820them with 0x), and so that modify_inode can set the inode generation 4821number. Also, there is now a new function command called logdump 4822which will dump an ext3 journal. 4823 4824Fixed a bug in debugfs so that quitting out of the pager doesn't kill 4825debugfs. 4826 4827Debugfs's dump command now stops immediately upon reporting a disk 4828read error. (Fixed a bug in ext2fs_file_read library routine which 4829caused debugfs not to stop.) (Debian bug #79163) 4830 4831On systems with /proc/mounts (mainly Linux systems), /proc/mounts is 4832checked before /etc/mtab is used, since /proc/mounts is more likely to 4833be accurate. 4834 4835Added portability fixes for Solaris and Linux/ia64. 4836 4837Various manual pages were clarified and cleaned up. (Fixed debian 4838bugs #63442, #67446, and #87216) 4839 4840 4841Programmer's notes: 4842------------------- 4843 4844The e2fsck message printer now supports %Iu and %Ig, which will print 4845out the inode's user and group owners, respectively. 4846 4847E2fsprogs now includes its own version of include/linux/ext2_fs.h, so 4848that no longer dependent on the system having the correct version of 4849the kernel header files. 4850 4851Added a new function to libext2, ext2fs_find_block_device(), which 4852searches the system (i.e., /dev, /devfs, /devices) for a pathname to a 4853device given its device number. 4854 4855Added a new function to libext2, ext2fs_sync_device, which centralizes 4856all of the places which might try to use the BLKFLSBUF or FDFLUSH 4857ioctls (and usually failing to define them since the system header 4858files don't usually do this for us, and we're trying to avoid usage of 4859kernel include files now). 4860 4861Added new utility programs in tests/progs: random_exercise and 4862hold_inode. They aren't built by default; they're useful for 4863exercising ext3 filesystem code. 4864 4865Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes 4866the filesystem close functions to only update the superblock, and to 4867not touch the block group descriptors. Needed by tune2fs when 4868modifying a mounted filesystem. 4869 4870Got rid of struct ext2fs_sb and replaced it with the standard struct 4871ext2_super_block from include/linux/ext2_fs.h. Note: this may break 4872source (but not binary) compatibility of some users of the ext2 4873library. Those applications should just simply do a global search and 4874replace of struct ext2fs_sb with struct ext2_super_block, and include 4875the new header file <ext2fs/ext2_fs.h> which defines it. 4876 4877The ino_t type has been renamed ext2_ino_t to protect applications 4878that attempt to compile -D_FILE_OFFSET_BITS=64, since this 4879inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an 4880unexpected ABI change. 4881 4882The Makefiles have been reworked so that "make check" can be run from 4883the top-level Makefile. 4884 4885Fix general gcc -Wall complaints and removed dead code. 4886 4887Remove use of NOARGS, because we assume everyone does ANSI C these 4888days. 4889 4890Added build-rpm script from sct. 4891 4892New functions ext2fs_image_{inode,super,bitmap}_{read,write} added 4893to support e2image. 4894 4895New function ext2fs_flush_icache which must be called if the 4896application program modifies the inode table blocks without going 4897through ext2fs_write_inode() interface. 4898 4899New ext2fs_check_mount_point() function, which will return the mount 4900point of a device if mounted. 4901 4902The io_channel abstraction now has an optional interface, 4903io_channel_write_range, which allows specific byte ranges to be 4904written. 4905 4906The unix_io IO channel now supports write-through caching, so that 4907journal creation is more efficient. 4908 4909Added x86 assembly language routines to support byte swapping, to 4910reduce executable size. 4911 4912Fixed bug in the utility program subst so that it's possible to 4913replace a substitution variable with a zero-length string. 4914 4915Fixed numbering e2fsck pass1 problem numbers; an extra zero had 4916slipped into some of the problem number. 4917 4918E2fsprogs 1.19 (July 13, 2000) 4919============================== 4920 4921Release the resize2fs program since the timeout before it could 4922be released under the GPL has finally expired. 4923 4924Add experimental support needed for the ext2 compression patches. 4925This requires compiling e2fsprogs with the --enable-compression flag 4926to the configure script. 4927 4928Added ext3 journalling support. E2fsck will run the journal (if 4929necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is 4930installed as a symlink to e2fsck. Fsck has been taught about ext3, 4931and treats it the same as ext2 in terms of the progress bar logic. 4932Dumpe2fs will display the superblock journaling information if the 4933filesystem has a journal. The ext2 library will now permit opening an 4934ext3 filesystem with the recovery flag set. This is necessary for 4935on-line dump's to work correctly, but there may be issues with this 4936working well since ext3 is much less agressive about syncing blocks to 4937the filesystem, since they're safe on the journal. 4938 4939Tune2fs and e2fsck have been changed to allow the mount_count check to 4940be disabled by setting max_mount_count to -1. (This was already 4941supported by the kernel.) 4942 4943Create a symbolic link for fsck.ext3, since the e2fsprogs utilities 4944are used for ext3 as well. 4945 4946Added internationalization support for e2fsprogs; must be enabled 4947by passing --enable-nls to configure. 4948 4949Always use the provided ext2fs header files to insulate ourselves from 4950kernel version changes. Which include files are used by e2fsprogs 4951have also been cleaned up to improve portability. 4952 4953Limit the number of times that e2fsck updates the progress bar so that 4954people who are booting using a 9600 baud console don't get swampped by 4955too many updates. 4956 4957Improved the loop detection algorithm in e2sck's pass #3 so that it is 4958much, much faster for large filesystems with a large number of 4959directories. 4960 4961The memory footprint for e2fsck is now slightly smaller than before. 4962 4963E2fsck now checks if special devices have a non-zero size, and offers 4964to clear the size field if it finds such an inode. 4965 4966E2fsck now checks if special devices have the append-only flag set, 4967and offers to clear the inode. 4968 4969E2fsck now properly handles some "should never fail" cases during a 4970bitmap copy in pass5. 4971 4972E2fsck now properly prints control characters in filenames as ^A .. ^Z. 4973 4974E2fsck now calculates the correct location of the backup superblock in 4975the case of filesystem blocksizes > 1k. 4976 4977Fixed a bug in e2fsck's calculation of the number of inodes_per_block 4978which normally didn't cause problems under most filesystem parameters, 4979but could cause a valid superblock to be rejected in extreme cases. 4980Other checks for validating superblock values were made more 4981stringent. 4982 4983Added non-destructive write testing to the badblocks program, courtesy 4984of David Beattie. The badblocks also now has an option to input the 4985current set of bad blocks, so that known bad blocks are skipped to 4986speed up the badblocks test. There is also a persistent rescan 4987feature which causes badblocks to run until it has completed some 4988number of passes without discovering any new bad blocks. 4989 4990Badblocks now checks to see if the device is mounted and refuses to do 4991the tests involving writing to the device if it is mounted. Also, 4992badblocks now allows the number of blocks to be checked to be 4993defaulted to the size of the partition. 4994 4995Fixed a bug in fsck which didn't allow non-root users to be able to 4996check filesystems if there were any LABEL= or UUID= entries in 4997/etc/fstab. 4998 4999The Hurd doesn't support the filetype filesystem feature. The mke2fs 5000program now makes sure that for the Hurd, the filestype feature is 5001turned off. E2fsck will check to see if the filetype feature is 5002turned on for Hurd filesystems, and offer to turn off the feature. 5003 5004Mke2fs now has a safety check to make sure the number of blocks do not 5005exceed 32 bits even on a 64 bit platform. 5006 5007Really fixed a bug in fsck to allow "fsck -As" to run interactive 5008fsck's. (For those people who like to do interactive fsck's in the 5009/etc/rc scripts!?!) 5010 5011Debugfs has a few new features: the rdump command, which will do a 5012recursive dump of a directory and all of its contents, and the lcd 5013command which does a local chdir (much like the ftp command of the 5014same name). In addition, the debugfs program and the open_filesystem 5015command now takes three new options: -b and -s, which allows the 5016blocksize and superblock location to be specified, and the -c option 5017which is used in catastrophic situations where the block group 5018descriptors are corrupt. If the -c option is specified, debugfs will 5019skip trying to read in the block and inode bitmaps. 5020 5021Debufs's lsdel command was fixed to handle bad blocks in the inode 5022table. 5023 5024A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use 50254 digit years. 5026 5027General improvements in error messages 5028 5029 - Mke2fs prints a sane error message if the partition size is zero 5030 (usually because the partition table wasn't reread by the 5031 kernel due to the partition being busy), instead of "invalid 5032 argument passed to ext2 library while initializing superblock". 5033 5034 - Fsck now prints more self-explanatory message if an invalid UUID= 5035 or LABEL= specification is passed to it. 5036 5037UUID library changed to use the LGPL. 5038 5039Fixed a bug in the UUID library where very rapid calls to the 5040time-based UUID generator could cause duplicate UUID's to be returned. 5041This was not a problem for e2fsprogs, but it could be a problem for 5042other users of the library. 5043 5044Make the UUID library more robust in the face of missing or an 5045improper /dev/urandom or /dev/random files. 5046 5047Added some random portability fixes for Solaris. 5048 5049Some minor man page updates. 5050 5051Fixed a memory leak in the ss library. 5052 5053 5054Programmer's notes: 5055------------------- 5056 5057We now try to use lseek64 and open64 from the LFS if possible. 5058 5059The 3rd parameter in e2p's print_flags is now a flags word, instead of 5060a boolean option. 5061 5062The mark and unmark bitmap functions now return the previous state of 5063the bit that was being changed, which is useful for some speed 5064optimizations. 5065 5066The following functions have been added to enhance the badblocks list 5067handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and 5068ext2fs_badblocks_equal. 5069 5070The ext2 header files now have the latest journalling fields to the 5071superblock. 5072 5073The ext2fs_mkdir function in libext2fs now properly backs out of error 5074conditions robustly. 5075 5076Cleaned up makefiles: 5077 - to cleanly compile with the -j flag. 5078 - so distclean removes all generated files. 5079 - so in case of an error while installing header files, the make aborts. 5080 5081Fix test_script so that it works correctly when compiling in the 5082source directory. 5083 5084The random UUID generation routine has been made slightly better in 5085the case where /dev/random doesn't exist. (Use of randomly-based UUID 5086is still not recommended if /dev/random doesn't exist, however; it's 5087better to use the time/ethernet MAC address UUID in this case.) 5088 5089Clean up the build process so it's more friendly in case of missing 5090directories. 5091 5092The ext2fs header file can now be #include'd into C++ programs. 5093 5094The e2p.h header file is now installed. 5095 5096Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. 5097 5098 5099 5100E2fsprogs 1.18 (November 10, 1999) 5101================================== 5102 5103Fix a core dumping bug in e2fsck if an imagic inode is present or 5104(more rarely) if the filesystem is badly corrupted enough that e2fsck 5105has to restart pass 1 processing. E2fsck now closes the filesystem 5106before freeing a large number of its data structures, so in the case 5107of future memory faults, at least the fixed filesystem will be fully 5108written out. 5109 5110If a filesystem doesn't support imagic inodes, and e2fsck discovers an 5111imagic inode, it will offer to clear the imagic flag. 5112 5113E2fsck will now offer to clear the immutable flag on special files 5114(device/socket/fifos) when running it in non-preen mode. 5115 5116E2fsck will now set the filetype when creating /lost+found, and when 5117connected orphaned inodes to /lost+found. 5118 5119Debugfs's ncheck and icheck commands now handles the case where there 5120are bad blocks in the inode table without bombing out. 5121 5122The badblocks list processing code has been made more efficiently for 5123appending a large number of (ordered) badblocks to the badblocks list. 5124 5125Some minor man page updates. 5126 5127Fsck now allows interactive e2fsck's when using fsck -As (not a common 5128mode, but some people like to do this in boot scripts for silly reasons). 5129 5130Programmer's notes: 5131------------------- 5132 5133The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet 5134with the problem code convention. 5135 5136The badblocks list regression test program has been updated to work 5137with previously made API name changes. 5138 5139The ext2fs_free() command now uses the new badblocks API to avoid 5140using the compatibility layer. 5141 5142Added new regression test cases; the run_e2fsck test script now 5143supports the ability for a test case to run a prepratory command 5144before running e2fsck. 5145 5146E2fsprogs 1.17 (October 26, 1999) 5147================================= 5148 5149Fixed nasty typo in fsck which caused parallelized fsck's to go into an 5150infinite loop. 5151 5152Fixed a bug in fsck where it used strncmp to compare a binary UUID, 5153thus potentially causing problems if a binary UUID contained a NULL 5154character. 5155 5156E2fsck now uses stricter checks for directory entries in pass 2: 5157zero-length filenames are not allowed; neither are 8 byte long 5158directory entries. 5159 5160The debugfs "dirty" command now clears the filesystem valid bit. 5161(Previously this just set the dirty-as-in-needs-writing-out-to-disk 5162bit in the in-core superblock image. The new functionality is more 5163what the user expects, and is more useful.) 5164 5165Added a debugging hook to test parallel fsck; if the environment 5166variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive 5167will be checked in parallel when they normally would not be. 5168 5169Programmer's notes: 5170------------------- 5171 5172Fixed some #ifdef's for compilation under the Hurd OS. 5173 5174Fixed minor W2K compatibility problems. 5175 5176Fixed some miscellaneous GCC warnings. 5177 5178 5179E2fsprogs 1.16 (October 22, 1999) 5180================================= 5181 5182Fixed a race condition bug in fsck; when printing a progress bar, if 5183checking multiple filesystems in parallel, it was possible for fsck to 5184send e2fsck a SIGUSR1 signal before e2fsck had installed its signal 5185handler, which would cause it to terminate with a signal 10. 5186 5187E2fsck now properly handles filesystems that have the 5188INCOMPAT_FILETYPE feature turned on. It can be used to convert a 5189filesystem into using or not using FILETYPE feature. 5190 5191E2fsck now properly handles filesystems that have the IMAGIC feature 5192turned on (this is used on Linux AFS servers). 5193 5194The mke2fs program now creates filesystems that have the filetype and 5195sparse_superblock features enabled by default, unless it is run on a 5196pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, 5197so there is now a new flag -O which allows the user to specify with 5198which features she would like to create the filesystem; "mke2fs -O 5199none" will create a filesystsem compatible with 2.0 kernels. 5200 5201The tune2fs program now has a -O option which allows the user to set 5202and reset "safe" filesystem features. Currently, the only ones which 5203allows to be modified are the filetype and sparse_superblock features. 5204Note setting or clearing either feature will require running e2fsck on 5205the filesystem afterwards. (n.b. Clearing the sparse_superblock feature 5206requires that there is enough free space on the filesystem for the 5207extra superblocks which will be created by e2fsck.) 5208 5209Debugfs can now set and print filesystem features in the superblock 5210using the "features" command. Dumpe2fs will print out the complete 5211set of features when listing the superblock. 5212 5213Dumpe2fs has new options -f (force) and -h (header-only). 5214 5215Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead 5216message to come up. This could happen when decrementing or 5217incrementing a link count could result in an overflow. 5218 5219Fixed a bug in e2fsck where the block count on the lost+found 5220directory would not be properly incremented when the directory was 5221expanded to the point where an indirect block needed to be allocated. 5222 5223E2fsck now makes some additional sanity checks on the superblock to 5224avoid crashing or giving a memory allocation error if some of the 5225values in the superblock are unresonable (but the superblock otherwise 5226looks valid). 5227 5228Fixed a bug in e2fsck where a very badly corrupted filesystem might 5229require two passes to completely fix the filesystem. This happened if 5230an inode claimed blocks that was part of the filesystem metadata 5231(typically, when garbage was written into an inode table or indirect 5232block, since this kind of filesystem corruption normally doesn't 5233happen otherwise). 5234 5235On the Alpha, glibc declares st_flags although it isn't actually used; 5236the configure script was improved to detect this case so that 5237e2fsprogs can avoid using the non-functional stat field. 5238 5239The manual pages were updated to use a more consistent formatting 5240style consistent with standard Unix man pages. Mke2fs's man page 5241added documentation for a few previously undocumented options. 5242 5243Fixed minor display bugs in tune2fs and mke2fs. 5244 5245Programmer's notes: 5246------------------- 5247 5248Improved portability of e2fsprogs to non-Unix systems (in particular, NT). 5249 5250Added features to parse and print feature strings into the e2p library. 5251(e2p_feature2string, e2p_string2feature, e2p_edit_feature). 5252 5253ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories 5254whose directory entries contain proper filetype information if the 5255filesystem supports it. 5256 5257ext2fs_link() now uses the low 3 bits of its flags parameter to pass 5258the directory entry filetype information. This is used to set the 5259directory entry filetype information if the filesystem supports it. 5260 5261Fixed a bug in ext2fs_expand_dir() where the block count in a 5262directory's inode would not be properly incremented when the directory 5263was expanded to the point where an indirect block needed to be 5264allocated. 5265 5266 5267E2fsprogs 1.15 (July 18, 1999) 5268============================== 5269 5270Add configuration checks so that e2fsprogs will compile cleanly on 5271Linux 2.3 kernels that have renamed i_version to i_generation. 5272 5273E2fsck now prints a progress/completion bar (and not just a simple 5274spinner) if the -C0 option is requested or if it receives a SIGUSR1 5275signal. Fsck will automatically manage the (potentially muliple) 5276e2fsck processes to print completion bars if it is given a -C option, 5277with the right thing happening if multiple filesystems are being 5278checked in parallel. 5279 5280Mke2fs now has better automatic hueristics to determine the filesystem 5281parameters to be used for a particular filesystem. Added a new option 5282-T which allows the user to specify how the filesystem is to be used, 5283which helps mke2fs do a better job selecting the filesystem parameters. 5284 5285Mke2fs now creates revision 1 filesystems by default, and with the 5286sparse superblock feature enabled. The sparse superblock feature is 5287not understood by Linux 2.0 kernels, so they will only allow read-only 5288mounts of filesystems with this sparse superblocks. 5289 5290Fix bug where if /dev/null couldn't be opened (should never happen), 5291e2fsck would hang in a tight loop. 5292 5293Make e2fsck handle the case where /lost+found isn't a directory. 5294 5295E2fsck now uses mallinfo if it exists to get accurate statistics about 5296its memory usage. 5297 5298Fix bug in e2fsck where it wouldn't check to see if a disconnected 5299inode had any problems before connecting it to /lost+found. 5300 5301Add check to e2fsck so it makes sure that total number of inodes in 5302the filesystem is a sane number. 5303 5304Fix fencepost error when clearing an the end of the block bitmap which 5305caused the last block in the bitmap not to get cleared. 5306 5307Cleaned up a number of messages in e2fsck: 5308 * The message "Group's #'s copy of the group descriptor..." 5309 was fixed so that the correct number would be displayed. 5310 * Added missing space in the "disk write-protected" error messsage 5311 * Cleaned up the error message printed when a non-interactive 5312 e2fsck needs to abort a check because the filesystem 5313 appears to be mounted. 5314 5315Added a new command-line utility, uuidgen, which will create and print 5316a UUID. 5317 5318Make debugfs's icheck command more robust by checking to make sure an 5319inode has valid blocks before interarting over the inode's blocks. 5320 5321UUID generation now uses a random-based scheme whenever possible to 5322prevent potential privacy problems. 5323 5324Man pages for all of the UUID functions in the lirbary were added. 5325 5326Fixed bug in fsck so it won't coredump if a filesystem not in 5327/etc/fstab is given to it. 5328 5329Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab 5330that most of the other mount utilities understands. 5331 5332Mke2fs will make a filesystem even if it appears mounted if the force 5333option is given. 5334 5335Dumpe2fs has new command-line options which allow a filesystem expert 5336to specify the superblock and blocksize when opening a filesystem. 5337This is mainly useful when examining the remains of a toasted 5338filesystem. 5339 5340The badblocks program has been updated to display correctly on disks 5341with large block numbers. 5342 5343The badblocks program no longer gives spurious errors when errors 5344occur on non-block boundaries, which is common if the blocksize is 5345larger than 1k. 5346 5347Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the 5348MKE2FS_SYNC environment variable is set. This is to work around a VM 5349bug in the 2.0 kernel. I've heard a report that a RAID user was able 5350to trigger it even using a 2.2 kernel, but hopefully it will not be 5351needed for most Linux 2.2 users. 5352 5353Fixed miscellaneous documentation and man pages. 5354 5355Programmer's notes: 5356------------------- 5357 5358Cleaned up functions such as pass1_get_blocks, pass1_read_inode which 5359in e2fsck's pass1.c really should have been static. 5360 5361The return value of the uuid_compare() function was changed to make it 5362match with the convetions used by strcmp, memcmp, and Paul Leach's 5363UUID sample document. 5364 5365The "make depend" process has now been made more automated; it now 5366automatically word-wraps the dependencies, and only replaces source 5367Makefile.in if there has been a change in the dependencies. Also, a 5368top-level "make depend" now recurses through all the subdirectories 5369automatically. 5370 5371The Makefile in .../util has been changed so that subst is built using 5372the native C compiler during a cross-compilation, since the subst 5373program is only used during the build process. Also add an explicit 5374rule to build util/subst by cd'ing to the correct directory and 5375running Makefile. 5376 5377The man directories are defined in terms mandir, so that the configure 5378script can override the location of the manual pages. 5379 5380The config files have been updated to recognize new machine types for 5381both the i386 and alpha families. 5382 5383Fsck has been modified so that it will accurately create an 5384fsck_instance even when the noexecute flag is set. This allows for 5385accurate debugging of the fsck pass structure. Also, when the verbose 5386flag is given twice, fsck will print debugging information about when 5387fsck is waiting for jobs to finish. 5388 5389 5390E2fsprogs 1.14 (January 9, 1999) 5391================================ 5392 5393Fix the fstab parsing code so that it can handle blank lines and 5394comment characters. Also, missing pass numbers need to be treated as 5395zero. 5396 5397Fixed a bug in e2fsck where under some circumstances (when e2fsck 5398needs to restart processing after fixing an egregious inconsistency) 5399it would try to access already freed memory. 5400 5401E2fsck now prints non-printable characters in directory entries and 5402pathnames using '^' and 'M-' notation. 5403 5404Fixed chattr so that it will ignore symbolic links when doing 5405recursive descent traversals. For both chattr and lsattr, no longer 5406print the version string unless the -V option is given. 5407 5408Allow the system administrator to directly specify the number of 5409inodes desired in the filesystem, for some special cases where this is 5410necessary. 5411 5412Fix portability problems so that e2fsprogs can be compiled under Linux 54131.2 systems and Solaris systems. 5414 5415Update the config.guess file with a more recent version that will 5416identify newer Linux platforms. 5417 5418Programmer's notes 5419------------------ 5420 5421Ext2fs_read_inode and ext2fs_write_inode will now return an error if 5422an inode number of zero is passed to them. 5423 5424E2fsprogs 1.13 (December 15, 1998) 5425================================== 5426 5427Fixed a bug in debugfs where an error messages weren't getting printed 5428when the ext2 library routines to read inodes returned errors in the 5429stat, cmri and rm commands. 5430 5431Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is 5432provided, it won't create an inode table smaller than the minimum 5433number of inodes required for a proper ext2 filesystem. 5434 5435Fsck now parses the /etc/fstab file directly (instead of using 5436getmntent()), so that it can distinguish between a missing pass number 5437field and pass number field of zero. This caused problems for 5438diskless workstations where all of the filesystems in /etc/fstab have 5439an explicit pass number of zero, and fsck could not distinguish this 5440from a /etc/fstab file with missing pass numbers. 5441 5442E2fsck will create a /lost+found directory if there isn't one in the 5443filesystem, since it's safer to create the lost+found directory before 5444it's needed. 5445 5446Fixed e2fsck so that it would detect bogus immutable inodes which 5447happen to be sockets and FIFO files, and offer to clear them. 5448 5449If a filesystem has multiple reasons why it needs to be checked, and 5450one of the reasons is that it is uncleanly mounted, e2fsck will print 5451that as the reason why the filesystem is being checked. 5452 5453Cleaned up the output routines of mke2fs so that it doesn't overflow 5454an 80 column display when formating really big filesystems. 5455 5456Added a sanity check to e2fsck to make sure that file descriptors 0, 54571, 2 are open before opening the hard disk. This avoids a problem 5458where a broken program might exec e2fsck with those file descriptors 5459closed, which would cause disastrous results if the kernel returns a 5460file descriptor for the block device which is also used by FILE * 5461stdout. 5462 5463Fixed up the e2fsck progress reporting functions so that the values 5464reliably reach 100% at the completion of all of the e2fsck passes. 5465 5466Fixed minor documentation bugs in man pages and usage messages. 5467 5468Programmer's notes: 5469------------------- 5470 5471Fixed a number of lint warnings in the ext2fs library and potential 5472portability problems from other OS's header files that might define 5473CPP macros for names like "max" and "min". 5474 5475ext2fs_badblocks_list_add() has been made more efficient when it needs 5476to grow the bad blocks list. 5477 5478Fixed a bug in e2fsck which caused it to dereference a freed pointer 5479just before exiting. 5480 5481Fixed the substition process for generating the mk_cmds and compile_et 5482scripts so that they will work outside of the build tree. 5483 5484Add sanity check to e2fsck so that if an internal routine 5485(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer 5486and causing a core dump. This should never happen, but... 5487 5488E2fsprogs 1.12 (July 9, 1998) 5489================================== 5490 5491E2fsprogs now works with glibc (at least with the version shipped wtih 5492RedHat 5.0). The ext2fs_llseek() function should now work even with 5493i386 ELF shared libraries and if llseek() is not present. We also 5494explicitly do a configure test to see if (a) llseek is in libc, and 5495(b) if llseek is declared in the system header files. (See standard 5496complaints about libc developers don't understand the concept of 5497compatibility with previous versions of libc.) 5498 5499The ext2fs library now writes out the block group number in each of 5500the superblock copies. This makes it easier to automatically 5501determine the starting block group of the filesystem when the block 5502group information is trashed. 5503 5504Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, 5505which means that e2fsprogs will ignore the high 8 bits of the 5506directory entry's name_len field, so that it can be used for other 5507purposes. 5508 5509Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. 5510E2fsprogs will now support filesystems with 64-bit sized files. 5511 5512Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. 5513 5514Added new program "e2label", contributed by Andries Brouwer. E2label 5515provides an easy-to-use interface to modify the filesystem label. 5516 5517Fixed bug so that lsattr -v works instead of producing a core dump. 5518 5519Fixed a minor bug in mke2fs so that all groups with bad superblock 5520backup blocks are printed (not just the first one). 5521 5522Mke2fs will check the size of the device, and if the user specifies a 5523filesystem size larger than the apparent size of the device it will 5524print a warning message and ask if the user wants to proceed. 5525 5526E2fsck has a new option -C, which sends completion information to the 5527specified file descriptor. For the most part, this is intended for 5528programs to use, although -C 0 will print a spinning character to the 5529stdout device, which may be useful for users who want to see something 5530happening while e2fsck goes about its business. 5531 5532Fixed a bug in e2fsck which could cause a core dump when it needs to 5533expand the /lost+found directory, and sometimes the bitmaps haven't 5534been merged in. Also fixed a related bug where ext2fs_write_dir_block 5535was used to write out a non-directory block. (Which would be bad on a 5536non-Intel platform with byte swapping going on.) 5537 5538Fixed bug in e2fsck where it would print a "programming error" message 5539instead of correctly identifying where a bad block was in used when 5540the bad block was in a non-primary superblock or block group 5541descriptor. Also fixed a related bug when sparse superblocks are in 5542use and there is a bad block where a superblock or block group 5543descriptor would have been in a group that doesn't include a 5544superblock. 5545 5546Fixed a bug in e2fsck (really in libext2fs's dblist function) where if 5547the block group descriptor table is corrupt, it was possible to try to 5548allocate a huge array, fail, and then abort e2fsck. 5549ext2fs_get_num_dirs() now sanity checks the block group descriptor, 5550and subsitutes reasonable values if the descriptors are obviously bogus. 5551 5552If e2fsck finds a device file which has the immutable flag set and the 5553i_blocks beyond the normal device number are non-zero, e2fsck will 5554offer to remove it, since it's probably caused by garbage in the inode 5555table. 5556 5557When opening a filesystem, e2fsck specially checks for the EROFS error 5558code, and prints a specific error message to the user which is more 5559user friendly. 5560 5561If the filesystem revision is too high, change the e2fsck to print 5562that this is either because e2fsck is out of date, or because the 5563superblock is corrupt. 5564 5565E2fsck now checks for directories that have duplicate '.' and '..' 5566entries, and fixes this corruption. 5567 5568E2fsck no longer forces a sync of the filesystem (with attendant sleep 5569calls) at all times. The ext2fs_flush() function now performs a sync 5570only if it needed to write data blocks to disk. 5571 5572Fixed a minor bug in e2fsck's pass1b's file cloning function, where 5573certain errors would not be properly reported. 5574 5575Updated and expanded a few points in the man pages which users 5576complained wheren't explicit enough. 5577 5578Added special case byte-swapping code if compiling on the PowerPC, to 5579accomodate the strange big-endian variant of the ext2 filesystem that 5580was previously used on the PowerPC port. 5581 5582 5583Programmer's notes: 5584------------------- 5585 5586Removed C++ keywords from the ext2fs libraries so that it could be 5587compiled with C++. 5588 5589E2fsck's internal organization has now been massively reorganized so 5590that pass*.c don't have any printf statements. Instead, all problems 5591are reported through the fix_problem() abstraction interface. E2fsck 5592has also been revamped so that it can be called as a library from a 5593application. 5594 5595Added new fileio primitives in libext2fs for reading and writing 5596files on an unmounted ext2 filesystem. This interface is now used by 5597debugfs. 5598 5599Added a new libext2fs function for mapping logical block numbers of 5600a file to a physical block number. 5601 5602Added a new libext2fs function, ext2fs_alloc_block(), which allocates 5603a block, zeros it, and updates the filesystem accounting records 5604appropriately. 5605 5606Added a new libext2fs function, ext2fs_set_bitmap_padding(), which 5607sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. 5608 5609The libext2fs functions now use a set of memory allocation wrapper 5610functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, 5611instead of malloc, free, and resize. This makes it easier for us to 5612be ported to strange environments where malloc, et. al. aren't 5613necessarily available. 5614 5615Change the libext2fs fucntion to return ext2-specific error codes 5616(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using 5617and depending on the existence of system error codes (such as EEXIST 5618and ENOENT). 5619 5620Renamed io.h to ext2_io.h to avoid collision with other OS's header 5621files. 5622 5623Add protection against ext2_io.h and ext2fs.h being included multiple 5624times. 5625 5626The types used for memory lengths, etc. have been made more portable. 5627In generla, the code has been made 16-bit safe. Added Mark 5628Habersack's contributed DOS disk i/o routines. 5629 5630Miscellaneous portability fixes, including not depending on char's 5631being signed. 5632 5633The io_channel structure has a new element, app_data, which is 5634initialized by the ext2fs routines to contain a copy of the filesystem 5635handle. 5636 5637ext2fs_check_directory()'s callback function may now return the error 5638EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to 5639really do the checking, despite the presence of the callback function. 5640 5641 5642E2fsprosg 1.11 (June 17, 1997) 5643============================== 5644 5645Fixed e2fsck to detect (previously ignored) conflicts between the 5646superblock or block group descriptors and block bitmaps, inode 5647bitmaps, and inode tables. 5648 5649Fixed bug in e2fsck so that when the message printed out when a block 5650or inode bitmap conflicts with other data, it has the correct group 5651number. 5652 5653Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed 5654to badblocks. This meant that not all of the filesystem was being 5655tested for bad blocks! 5656 5657Fixed an array boundary overrun case which cropped up in 5658ext2fs_badblocks_list_test when a user tried running "mke2fs -c 5659-b 4096". 5660 5661Adjusted the number of columns printed by mke2fs when displaying the 5662superblock backups to avoid running over 80 columns when making a 5663really big filesystem. 5664 5665Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, 5666dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar 5667fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). 5668 5669Programmer's notes: 5670------------------- 5671 5672Fixed install rule in lib/ss so that ss_err.h is actually getting 5673installed. 5674 5675Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting 5676bassed back to the caller. 5677 5678Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been 5679setting the current inode number (which meant this function wasn't 5680working at all). 5681 5682Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all 5683blocks in the bitmap when increasing the size of the bitmap. 5684 5685Changed the initial number of blocks allocated by ext2fs_init_dblist() 5686to be more realistic. 5687 5688Added a new function ext2fs_allocate_group_table, which sets up the 5689group descriptor information (and allocates inode and block bitmaps, 5690and inode tables for a particular group). The function was created by 5691factoring out code form ext2fs_allocate_tables(). 5692 5693Added a new function ext2fs_move_blocks which takes a bitmap of the 5694blocks to be moved, and moves them to another location on the 5695boardboard. 5696 5697Make the unix_io channel's io_channel_flush implementation calls sync() 5698to to flush the kernel buffers to disk. 5699 5700Added a new function ext2fs_dblist_count returns the number of 5701directory blocks in dblist. 5702 5703 5704E2fsprogs 1.10 (April 24, 1997) 5705=============================== 5706 5707Mke2fs once again defaults to creating revision #0 filesystems, since 5708people were complaining about breaking compatibility with 1.2 kernels. 5709Warning messages were added to the mke2fs and tune2fs man pages that 5710the sparse superblock option isn't supported by most kernels yet (1.2 5711and 2.0 both don't support parse superblocks.) 5712 5713Added new flag to mke2fs, -R <raid options>, which allows the user to 5714tell mke2fs about the RAID configuration of the filesystem. Currently 5715the only supported raid option is "stride" which specifies the width 5716of the RAID stripe. 5717 5718Fixed bug in e2fsck where pass1b would bomb out if there were any 5719blocks marked bad in the inode table. 5720 5721Fixed rare bug in mke2fs where if the user had a very unlucky number 5722of blocks in a filesystem (probability less than .002) the resulting 5723filesystem would be corrupt in the last block group. 5724 5725Fixed bug where if e2fsck tried to allocate a block to fix a 5726filesystem corruption problem and the filesystem had no free blocks, 5727ext2fs_new_block() would loop forever. 5728 5729The configure script now checks explicitly to see if "-static" works, 5730since that can't be assumed to be true --- RedHat doesn't install 5731libc-static by default. 5732 5733Fixed bug in libext2's block iterator functions where under some 5734cirmcustances, file with holes would cause the bcount parameter to the 5735callback function to be incorrect. This bug didn't affect any of 5736e2fsprogs programs, but it was discovered by Paul Mackerras, the 5737author of the PPC boot loader. 5738 5739Removed use of static variables to store the inode cache in libext2fs. 5740This caused problems if more than one filesystem was accessed via 5741libext2fs (static variables in libraries are generally a bad idea). 5742Again, this didn't affect e2fsprogs programs, but it was discovered by 5743Paul Mackerras. 5744 5745Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 5746will compile cleanly with 1.2.13 kernels (even with a.out shared 5747libraries!) 5748 5749Programmer's notes: 5750------------------- 5751 5752Added new functions to duplicate an ext2 filesystem handle, and its 5753associated substructure. New functions: ext2fs_dup_handle(), 5754ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). 5755Other structures, such as the io_channel and the inode_cache, now have 5756a ref count so that they only get freed when they are no longer used 5757by any filesystem handle. (These functions were added as part of the 5758development effort for an ext2 resizer). 5759 5760E2fsprogs 1.09 (April 14, 1997) 5761=============================== 5762 5763Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was 5764accidentally introduced in the 1.08 release. The overhead calculation 5765was accidentally removed, which caused ext2fs_initialize() to not 5766notice when the filesystem size needed to be adjusted down because 5767there wasn't enough space in the last block group. 5768 5769Fixed bug in version parsing library routine; it was always parsing 5770the library version string, instead of using the passed-in string. 5771 5772Clarified chattr man page. 5773 5774E2fsprogs 1.08 (April 10, 1997) 5775=============================== 5776 5777E2fsck 1.07 was very slow when checking very large filesystems with a 5778lot of files that had hard links (i.e., news spools). This was fixed 5779by seriously revamping the icount abstraction. Added a formal test 5780suite for the icount abstraction. 5781 5782Debugfs now has a "-l" option to the "ls" command, which lists the 5783inode number, permissions, owner, group, size, and name of the files 5784in the directory. 5785 5786Fix a bug in e2fsck where when a directory had its blocks moved to 5787another location during the pass 1b processing, the directory block 5788list wasn't updated, so pass 2 wouldn't check (and correct) the 5789correct directory block. 5790 5791E2fsck will now treat inodes which contain blocks which are claimed by 5792the filesystem metadata by treating them as multiply claimed blocks. 5793This way, the data in those blocks can be copied to a new block during 5794the pass 1b--1d processing. 5795 5796E2fsck will attempt to determine the correct superblock number and 5797display it in the diagnostic and warning messages if possible. 5798 5799Add support for a new (incompatible) feature, "sparse_super". This 5800feature reduces the number of blocks which contain copies of backup 5801superblocks and block group descriptors. (It is only an incompatible 5802feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now 5803support a new -s option; e2fsck will recognize filesystems built with 5804this feature turned on. 5805 5806E2fsck now checks the library to make sure is the correct version, 5807using new library functions. (This helps to diagnose incorrectly 5808installed e2fsprogs distributions.) 5809 5810Dumpe2fs now prints more information; its now prints the the 5811filesystem revision number, the filesystem sparse_super feature (if 5812present), the block ranges for each block group, and the offset from 5813the beginning of the block group. 5814 5815Mke2fs now distributes the inode and block bitmap blok so that the 5816won't be concentrated in one or two disks in RAID/striping setups. 5817Also, if the user chooses a 2k or 4k block group, mke2fs will try to 5818choose the largest blocks per group that be chosen. (For 2k blocks, 5819you can have up to 16384 blocks/group; for 4k blocks, you can have up 5820to 32768 blocks/group.) Previously mke2fs would not allow 5821specification of more than 8192 blocks per group, even if you were 5822using a 2k or 4k block group. 5823 5824Programmer's notes: 5825------------------- 5826 5827Added a new function ext2fs_create_icount2() which takes a "hint" 5828argument. This hint argument presets the icount array with the list 5829of inodes which actually need to be in the icount array. This really 5830helps to speed up e2fsck. 5831 5832Added a new function ext2fs_icount_validate() which checks the rep 5833invariant for the icount structure. This is used mostly for testing. 5834 5835The error mesasage given when a bad inode number is passed to 5836test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of 5837EXT2FS_UNMARK_ERROR). 5838 5839Added a new function ext2fs_set_dir_block which sets the block of a 5840dblist entry, given the directory inode and blockcnt. 5841 5842Added a new function ext2fs_get_library_version() which returns the 5843current library version, and ext2fs_parse_version_string() which 5844returns a version number based on a e2fsprogs version string. 5845 5846The icount functions will return EINVAL if the passed in inode number 5847is out of bounds. 5848 5849E2fsprogs 1.07 (March 9, 1997) 5850============================== 5851 5852E2fsck is now uses much less memory when checking really large 5853filesystems (or rather, filesystems with a large number of inodes). 5854Previously a filesystem with 1 million inodes required 4 megabytes of 5855memory to store inode count statistics; that storage requirement has 5856now been reduced to roughly half a megabyte. 5857 5858E2fsck can now properly deal with bad blocks appearing inside the 5859inode table. Instead of trying to relocate the inode table (which 5860often failed because there wasn't enough space), the inodes in the bad 5861block are marked as in use. 5862 5863E2fsck will automatically try to use the backup superblocks if the 5864primary superblocks have a bad magic number or have missing meta-data 5865blocks (or meta-data blocks which are out of range). 5866 5867E2fsck's pass 3 has been made more efficient; most noticeable on 5868filesystems with a very large number of directories. 5869 5870Completely revamped e2fsck's system of printing problem reports. It 5871is now table driven, to make them more easily customizeable and 5872extendable. Error messages which can be printed out during preen mode 5873are now one line long. 5874 5875Fixed e2fsck's filesystem swapping code so that it won't try to swap 5876fast symbolic links or deleted files. 5877 5878Fixed e2fsck core dumping when fixing a filesystem which has no 5879directories (not even a root directory). 5880 5881Added a check to e2fsck to make sure that the length of every 5882directory entry is a multiple of 4 (since the kernel complains if it 5883isn't). 5884 5885Added a check to e2fsck to make sure that a directory entry isn't a 5886link to the root directory, since that isn't allowed. 5887 5888Added a check to e2fsk to now make sure the '.' and '..' directory 5889entries are null terminated, since the 2.0 kernel requires it. 5890 5891Added check to write_bitmaps() to make sure the superblock doesn't get 5892trashed if the inode or block bitmap is marked as being block zero. 5893 5894Added checking of the new feature set fields in the superblock, to 5895avoid dealing with new filesystem features that this package wasn't 5896set up to handle. 5897 5898Fixed a fencepost error in ext2fs_new_block() which would occasionally 5899try to allocate a block beyond the end of a filesystem. 5900 5901When the UUID library picks a random IEEE 802 address (because it 5902can't find one from a network card), it sets the multicast bit, to 5903avoid conflicting with a legitimate IEEE 802 address. 5904 5905Mke2fs now sets the root directory's owner to be the real uid of the 5906user running mke2fs. If the real uid is non-zero, it also sets 5907the group ownership of the root directory to be the real group-id of 5908the user running mke2fs. 5909 5910Mke2fs now has more intelligent error checking when it is given a 5911non-existent device. 5912 5913When badblocks is given the -vv option, it now updates the block that 5914it is currently testing on every block. 5915 5916Fixed a bug in fsck where it wouldn't modify the PATH envirnoment 5917currently correctly if PATH wasn't already set. 5918 5919Shared libraries now built with dependencies. This allows the shared 5920library files to be used with dlopen(); it also makes the transition 5921to libc 6 easier, since ld.so can tell which libc a particular shared 5922library expects to use. 5923 5924Programmer's notes: 5925------------------- 5926 5927Added new abstraction (defined in dblist.c) for maintaining a list of 5928blocks which belongs to directories. This is used in e2fsck and other 5929programs which need to iterate over all directories. 5930 5931Added new functions which test to see if a contiguous range of blocks 5932(or inodes) are available. (ext2fs_*_bitmap_range). 5933 5934Added new function (ext2_inode_has_valid_blocks) which returns true if 5935an inode has valid blocks. (moved from e2fsck code). 5936 5937Added new function (ext2fs_allocate_tables) which allocates the 5938meta-data blocks as part of initializing a filesystem. (moved from 5939mke2fs code). 5940 5941Added a new I/O manager for testing purposes. It will either allow a 5942program to intercept I/O requests, or print debugging messages to 5943trace the activity of a program using the I/O manager. 5944 5945The badblocks_list functions now store the bad blocks in a sorted 5946order, and use a binary search to speed up badblocks_list_test. 5947 5948The inode scan function ext2fs_get_next_inode() may now return a soft 5949error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in 5950those cases where part of an inode table is missing or there is a bad 5951block in the inode table. 5952 5953Added a new function (ext2fs_block_iterate2) which adds new arguments to 5954the callback function to return a pointer (block and offset) to the 5955reference of the block. 5956 5957Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an 5958application to jump to a particular block group while doing an inode 5959scan. 5960 5961The badblocks list functions were renamed from badblocks_* to 5962ext2fs_badblocks_*. Backwards compatibility functions are available 5963for now, but programs should be modified to use the new interface. 5964 5965Some of the library functions were reorganized into separate files to 5966reduce the size of some programs which statically link against the 5967ext2 library. 5968 5969Put in some miscellaneous fixes for the Alpha platform. 5970 5971 5972E2fsprogs 1.06 (October 7, 1996) 5973================================ 5974 5975Fixed serious bug in e2fsck: if the block descriptors are bad, don't 5976smash the backup copies in ext2fs_close(). (The problem was that when 5977e2fsck -p discovered the problem, while it was closing the filesystem 5978and exiting, it was also blowing away the backup superblocks on the 5979disk, which was less than friendly.) We now make it the case that we 5980only write out the backup superblock and the back block descriptors if 5981the filesystem is completely free from problems. 5982 5983Fixed a bug in block_interate in the lib/ext2fs library which caused 5984e2fsck to fail on GNU Hurd-created filesystems. 5985 5986Add support for Linux/FT's bootloader, which actually uses 5987EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want 5988to clear the inode. 5989 5990Add support for the "A" (no atime update) attribute. (Note: this 5991attribute is not yet in production kernels.) 5992 5993The test suite is not automatically run when doing a "make all" from 5994the top level directory. Users should manually run "make check" if 5995they wish to run the test suite. 5996 5997Upon a preenhalt(), make the printed message more explicit that 5998running e2fsck "MANAULLY" means without the -p or -a options. 5999 6000In e2fsck, if a disconnected inode is zero-length, offer to clear it 6001instead of offering to connect it to lost+found. 6002 6003In e2fsck, if a filesystem was just unmounted uncleanly, and needs 6004e2fsck to be run over it, change e2fsck to explicitly display this 6005fact. 6006 6007For dumpe2fs and e2fsck, cause the -V option to print out which 6008version of the ext2fs library is actually getting used. (This will 6009help detect mismatches of using a 1.06 utility with a 1.05 library, 6010etc.) 6011 6012Programmers' notes: 6013------------------- 6014 6015EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits 6016the naming convention. 6017 6018In ext2fs_initialize(), make sure the description for the inode bitmap 6019is correctly initialize. 6020 6021Fixed minor type typo in ext2fs_allocate_generic_bitmap(); 6022 6023E2fsprogs 1.05 (September 7, 1996) 6024================================== 6025 6026Add support for new fields in the ext2 superblock --- volume name, 6027volume UUID, and last mounted field. Dumpe2fs displays these fields, 6028tune2fs and mke2fs allows you to set them. E2fsck will automatically 6029generate a UUID for those volumes that don't have them. 6030 6031Put in support for e2fsck to recognize HURD specific ext2 features --- 6032most notably, the translator block. The e2fsprogs tools will now use 6033the creator_os field in the superblock to correctly handle different 6034OS-specific variants of the ext2 filesystem. 6035 6036E2fsck now fixes inodes which have a the deletion time set, but which 6037have a non-zero i_link_count field by offering to clear the deletion 6038time. Previously e2fsck assumed that the inode was deleted (per 0.3c 6039ext2 kernel behavior) and offered to unlink the file. 6040 6041If e2fsck sets the clean bit, but nothing else, set the exit code 6042FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it 6043set the filesystem valid bit when it was previously cleared. :-) This 6044was needed to make the HURD fsck driver happy. 6045 6046If the user refuses to attach an unattached inode, e2fsck will no 6047longer set the inode's link count. Otherwise, the inode would end up 6048getting marked as unused, which might cause loss of data later. 6049 6050Make the message issued by e2fsck when the superblock is corrupt less 6051confusing for users. It now mentions that another reason for the 6052"corrupt superblock" message might be that the partition might not be 6053an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) 6054 6055Make the libext2 library more robuest so that e2fsck won't coredump on 6056an illegal superblock where the blocksize is zero. (f_crashdisk is 6057the test case). 6058 6059By default, create filesystems where the default checkinterval is 6 6060months (180 days). Linux servers can be robust enough that 20 reboots 6061can be a long, long time. 6062 6063Added configure flag --enable-old-bitops, which forces the bitops to 6064use the old (native) bitmask operations. By default on the sparc 6065platform, the standard ext2 bit ordering is now used. 6066 6067Added a new feature to e2fsck to byte-swap filesystems; this can be 6068used to convert old m68k filesystems to use the standard byte-order 6069storage for the superblock, inodes, and directory blocks. This 6070function is invoked by using the '-s' option to e2fsck. 6071 6072Debugfs's "dump" command has been enhanced so that it writes out the 6073exact size of the file so that the nulls at the end of the file are 6074eliminated. The command also accept a new "-p" option which will 6075attempt preserve to preserve the ownernship, permissions, and 6076file modification/access times. 6077 6078Debugfs has two new options, -f and -R. The -R option allows the user 6079to execute a single debugfs command from the command line. The -f 6080option allows the user to specify a "command file" containing debugfs 6081commands which will get executed. 6082 6083Dumpe2fs now pretty prints the check interval, instead of just 6084printing the check interval as a number of seconds. 6085 6086Fix bugs in debugfs: the params command when no filesystem is opened 6087no longer causes a core dump. It is now possible to unlink a file 6088when a pathame containing a '/' is specified. 6089 6090Tune2fs has a new -C option which sets the number of times the 6091filesystem has been mounted. 6092 6093Fix the chattr '-v' option so that it actually works. Chattr was 6094being buggy about the -v option parsing. 6095 6096Programmers' notes: 6097------------------- 6098 6099The directory lib/uuid contains a set of library routines to generate 6100DCE compatible UUIDs. 6101 6102Extended ext2fs_namei() to handle symbolic links. Added new function 6103ext2fs_nami_follow() which will follow last symbolic link in the case 6104where the pathname points to a sym link. 6105 6106The ext2fs_block_iterate function will now return the HURD translator 6107block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the 6108iterator to return data blocks only. The ext2fs.h file now defines 6109constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and 6110BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block 6111count field of the iterator callback function. 6112 6113The test script driver now takes an optional second argument, which is 6114the test case to be run. This allows you to run a test case without 6115needing to run the entire test suite. 6116 6117On Linux ELF systems, install the .so files in the correct places 6118(/usr/lib). The .so files must be stored in the same directory as the 6119.a files. 6120 6121Fixed miscellaneous HURD compilation issues with header file being 6122included in the right order. 6123 6124Fixed debugfs so that it resets optind to zero, not one, since setting 6125optind to zero is more correct. 6126 6127 6128E2fsprogs 1.04 (May 16, 1996) 6129============================= 6130 6131First "official" (1.03 was a limited release only) to support building 6132e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 6133kernels). 6134 6135This package includes a RPM specs file, that it can be built using the 6136RedHat Package Manager. 6137 6138E2fsck now prints a hint that if there are lots of incorrectly located 6139inode bitmaps, block bitmaps, and inode table blocks, the user might 6140want to try using e2fsck -b 8193 first, to see if that fares any 6141better. 6142 6143For ext2 filesystem written with the hurd, debugfs will now print out 6144the translator field when printing an inode structure. 6145 6146Lots of miscellaneous linking/installation cleanups: 6147 6148 Libraries are now linked using a relative pathname, instead of 6149 relying on -L working correct. It doesn't, in many cases, including 6150 current versions of GNU ld. This guarantees that the build tree is 6151 linking with the right libraries, instead of the ones installed in 6152 /usr/lib. 6153 6154 Header files, man pages, and the et/ss shell scripts are now 6155 generated using a custom substitution script, instead of relying on 6156 the configure script. This prevents needless recompilation of 6157 files; in addition, the custom substitution script is much faster. 6158 6159 e2fsck may now be linked dynamically, by using the 6160 --enable-dynamic-e2fsck flag to configure. This is not recommended, 6161 since it increases e2fsck's dependence on other files, but some 6162 people need to save disk space, and other critical programs on their 6163 systems were being linked dynamically anyway. 6164 6165 Programs such as fsck which didn't need to be linked against 6166 libext2fs (or mke2fs which didn't need to be linked against libe2p) 6167 only link against libraries they actually need. Otherwise, those 6168 programs would require the presense of libraries that otherwise 6169 could be removed from a rescuse diskette. 6170 6171 The ss include files are now installed correctly so they can 6172 actually be used by another package. 6173 6174 If the profiling libraries are built, they are now installed on a 6175 "make install-libs". 6176 6177 6178E2fsprogs 1.03 (March 27, 1996) 6179=============================== 6180 6181Change the m68k bit numbering for bitmasks to match the bit numbering 6182used by all other ext2 implementations. (This change was requested by 6183the m68k kernel development team.) 6184 6185Support (in-development) filesystem format revision which supports 6186(among other things) dynamically sized inodes. 6187 6188Fixed a bug in the ext2 library so that an intelligent error is 6189returned if mke2fs is run with a ridiculously small number of blocks 6190for a partition. 6191 6192Fixed a bug in the ext2 library which required that the device be 6193openable in read/write mode in order to determine its size. This 6194caused e2fsck -n to require read/write access when it was not 6195previously necessary. 6196 6197Fixed a bug in e2fsck which casued it to occasionally fail the test 6198suite depending on which version of the floating point library it was 6199using. 6200 6201Fixed a bug in e2fsck so that it now halts with a fatal error when 6202certain superblock consistency checks fail. Previously it continued 6203running e2fsck, with some potential confusing/damaging consequences. 6204 6205Added new flag to fsck which allows the root to be checked in parallel 6206with other filesytems. This is not the safest thing in the world to 6207do, but some system administrators really wanted it. 6208 6209Fixed -Wall flames in lib/ss. 6210 6211 6212E2fsprogs 1.02 (January 16, 1996) 6213================================= 6214 6215Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. 6216 6217Change e2fsck to print statistics of how many non-contiguous files are 6218on the system. Note that a file which is larger than 8k blocks, it is 6219guaranteed to be non-contiguous. 6220 6221In mke2fs, print a warning message if a user tries to format a whole 6222disk (/dev/hda versus /dev/hda1). If a user really wants to format a 6223whole disk, the -F (force) option forces mke2fs to format a whole disk 6224as a filesytem. 6225 6226Fix a bug in fsck where in some cases it might start checking 6227partitions in the next pass before it finishes checking partitions in 6228the current pass. This still won't cause two partitions on the same 6229disk will be checked, so it's rarely a problem in real life. 6230 6231Patch lsattr so that it won't hang when checking a named pipe. 6232 6233Minor compilation fixes: 6234 * Fix the order of libraries that were linked in debugfs. 6235 * Allow the sources to be compiled with -ansi turned on. 6236
